Let's take a look at that ground symbol. If you would like to support me to keep Simply Electronics going, you can become a Patron at / simplyelectronics
Unfortunately, no. This video is misleading and a little wrong; ground is more complicated than that. Here is a more complete explanation. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-KXjSSvIrKUw.html
Well, in a simple case. But if you imagine more batteries in series, then it's the last one in that will represent the theoretical ground, theoretical, as it is not really grounded, so between that and the real ground point there can be potential difference.
@@datle5585 Well, I assume if negative is connected to the real ground too, then it would be. But it is not 0V potential ever as charged by many things, e.g. particles from space. But good enough. :) Hopefully it is clarifying.
I really like your video but there seems to me a misconception about electrons: 1:05 electrons don't ever get rid of their charge (unless they meet positrons which doesn't usually happen in circuits) and they don't carry any kind of "additional charge" they could get rid of but they carry specific quantity of charge - the elementary charge this was discovered in 1909 by Robert Millikan. More here: en.wikipedia.org/wiki/Elementary_charge 5:16 electrons do always carry elementary charge
There is a very serious basic flaw in this video. The author said electrons flows from the +ve terminal to the negative; it is wrong in all manner! The current flow from +ve to -ve is only a historical convention - thus called conventional current flow. We now know current is actually a flow of electrons that goes from the -ve terminal to the +ve (of a battery). In AC current direction reverses every half cycle.
I suppose what he should have stated is that the difference of potential held by that excess charge is lost when they return to the earth. But apparently, even that is not a completely accurate statement since according to the following thread on Answers.com electrons don’t actually flow (or move) through a circuit at all: www.answers.com/Q/Why_is_electron_flow_in_the_opposite_direction_of_current.
He's said it right in many other videos(how battery works - electronics basics 3, for example). He may has slipped here but it happens. We just have to point it out to him but not attack him. Great work, keep it up!
Mate, you are doing a great job! This is probably the best channel in RU-vid regarding electronics. I admire how simply you explain otherwise rather difficult concepts. Thank you, and I hope you keep this channel rolling. :)
Conventional current flows from positive to negative voltages. In reality, electrons flows from negative to positive.. here in the video says the electrons go otherwise.. my head blew
the lack of an electron at a position where one could exist in an atom or atomic lattice, so the empty spaces that electrons leave while moving to the positive side are called holes is the positive current or conventional current or hower you want to call it.
Braden Z Agree, and it is very important to have this straight. For example, one can’t understand vacuum tubes or transistors without actually knowing which way electrons and ‘positive holes’ flow. So, in this example, or any ground, electrons are actually ‘sucked out’ of the ground.
TV? I am an industrial automation electronics engineer. If I need schematics, they generally include internal schematics of specific components such as ICs and many kinds of modules. Google is usually all I need. Sorry I couldnt help.
A lot of viewers are jumping on the "electron flow" direction. (1) In the beginning he told that it is conventional current direction. (2) Just think those moving dots as +ve charges.
SO FANTASTIC VIDEO man !!! I was spending 5 days thinking " this is an open circuit , how the hell can it run in the first place " , google all over the place but they just explain that ground is for voltage reference , but no one have explained it's very core meaning . Keep on the good work!
Thank you for one of most lucid explanations of ground - I think I finally understand the concept after close twenty years trying to learn electronics.
You can use the term "electron" when talking about real flow, but when using conventional current terms is better to simply use the word "charge". So charges flow from + to -.
Wow! Finally, I get to understand why I don't see the line connecting back to the negative side of the power supply. I was really confused. Thank you very much for explaining it. I am currently studying a basic electronics course on UDEMY, but instructor did not explain this.
Great job man! I have just started to learn about electricity at school an about the important laws. I think that your channel will teach me many things. One question What is the name of the programme you use for this animations?
That’s great information! Glad to know that ground symbols are essentially saying they’re returning to the negative side of the power source without causing clutter.
as usual no-one can explain these things completely and clearly, one must watch dozens of videos and put the info together to really see... this video comes closest than any other I have watched.
Sir, the video was indeed helpful . Thank you😊. Can you please tell the name of the application you used for designing the circuit as I need it for my college project. Thank you!
Very well explained. Finally I found a tutorial the clear this out for me. What is that software that you are using? It looks handy to draw circuits schematics.
I understand that the earth (i.e. ground) can serve as an infinite supply from which a circuit may draw electrons or an infinite sink into which a circuit may dump electrons. But, does ground when used as a practical (as opposed to theoretical) component within an actual circuit implementation possess a lesser (or greater) resistance / impedance to the flow of electrical current?
is it the same when we say the terminal is connected to earth or is earthed even though there is no such earth where it needs to get connected like house hold wirings.
Ha! Once again..learned something new. I had no idea you could add multiple ground points in every circuit. I have been adding them as you first demonstrated, with them all connected. Thanks!
I always wanted to ask this to my electrotechnic teacher about how could the current go to the ground, from the moment that we need a closed circuit in oder to have current to pass. Because as we know (in theory), without closed circuit there is no possibility for current to circulate. So that´s why whenever the current goes to the ground, we still have a ´closed circuit´. Right?
This is the highest amount of likes I’ve ever seen on one of your videos. (And it’s a really low amount). Incase anyone didn’t get it, this is a compliment.
do bridge rectifier negative side must be insulated from earth ground? because in schematic it will short one of the diode because transformer connected to ground too?
Hi. I like your videos. I have a question. You said that electrons actually go from negative to positive. So If the negative is connected to the ground how can the electrons go through the circuit?
this is because the convention is that current flows from positive pole to the negative pole (and respectively to the ground which also 0 V, just like the negative pole). Scientifically although, the electrons flow from the negative pole to the positive pole. Thus the explanation he gives in the video is not entirely correct, because the electrons don't flow to the ground, but the current flows to the ground. The electrons are actually flowing from ground to the positive pole. However, while using a battery, there is no physical ground, because the circuit isn't connected to earth. As consequence the negative pole of the battery is considered as ground. The reason why there always is a ground symbol in his circuits is because the software EveryCircuit requires you to add a ground no matter what voltage source you use.
In a DC circuit the "ground" is not a connection to physical earth (PE) but rather a "common" point of reference for measuring voltage. Ground/Common/0V are more often than not used interchangeably. I prefer 0V.
Then what is "current"? Isn't current the flow of electrons themselves? That seems to upend this whole discussion. It's very frustrating to people trying to learn when these inconsistencies are thrown about like it doesn't matter. It does.
Richard Forester Current is the flow of electricity. Electrical flow is opposite to electron flow. Think of electricity as tension moving backwards from a locomotive to the wagons and electrons as the wagons themselves. The tension moves much faster than the train. Similarly, electrons move slower than crawling, whereas current moves at the speed of light.
Hak MengHeang, the program's called EveryCircuit. It comes with a trial, that won't let you make more than a five element circuit at first, then expires and asks for $14.99.
hi. I find this very confusing because on other videos i see illustrations showing electricity flowing from the negative to the + For example on a AA battery the the electric flows from the - side to the + side. however on this video at time 2:17 it is stating that electricity flows from + to - Please help explain this? on this video it states that electricity flows from - to + /watch?v=2BafNGDnxZw
So when drawing a schematic consider conventional current flow so you can ground the negative side instead of drawing loads of lines? In circuitry ground only exists purely for schematic purposes? In reality the only grounding would be on screened cabling to dissipate electrical noise?
I have two questions. Why on this schematic the electrons flow from + to - and in previous videos it is shown exactly the opposite? For example in "How Batteries Work - Electronics Basics 2". Why do you put ground symbol in completely closed circuits in all previous videos?
What about just an horizontal bar as ground symbol? This is what i think is used outside the US. I am not sure if you say electrons go to ground, as they are negative, thus beeing repelled. Did you mean charge instead? Anyway good videos!
@@ellewharton7394 2:08 he specifically says "using Conventional Current..." which is terminology you will want to get familiarised with, if you haven't yet.
@@LeeValentine001 Not even in conventional current electrons travel to the negative side, as negatives repel each other. In conventional current positive charges travel to the negative side. You may want to familiarise yourself with conventional current before suggesting other people do.
your tutorial is really helpful. sir I was having a problem of how to interpret a schematic circuit with capacitor , one of its terminal connected to the ground. My question is where do I have to terminate that terminal given that all other components on the circuit diagram have connection to the negative terminal of the power supply . would it be right to directly connect the that ground point of the capacitor to the negative.
+sheku Sheriff depends what your circuit is, if positive terminal of the capacitor is connected to something, connect it the the same ground point of the component it's connected across. For example, I have a capacitor with its positive terminal connected to the positive pin on an IC, therefore it would make sense for me to connect the negative terminal to the ground pin of my IC. For more complex circuits with multiple power rails, you would need to ensure you connect the cap across the correct rail to ensure the correct voltage is supplied.
How about in the case wherein, the positive terminal of the capacitor connected to the positive terminal of the power source; let say a battery. should I connect the negative terminal of that capacitor that has been grounded to that of the negative of the battery?
