Make a Voltage Divider - Simply Making 

In high school (over 20 years ago) I took one electric class and it came so natural. Best grade in the whole grade, blah, blah, blah. But parents always want what they think is best so this subject really wasn't taken serious. Now, as a hobby, almost anything electric is within my top 3 favorite things. However, since chasing knowledge in this field wasn't my objective 20+ years ago, I find myself mid age with a sudden thirst for this subject. The best lesson (other than don't electrocute yourself) that I learned, actually taught myself is that winging this subject when attempting to accomplish a successful goal just will not cut it. Sure a broken clock is right 2 times everyday but that clock should be in operating order to assure it's time is correct (or within acceptable margin of error.) No more half measures, I failed a project today that a substantial effort was wasted. Thus, this way, the way of equations, no estimations is the route that leads to a successful goal obtained. In fact, had I simply remembered this very information in this video some of the most valuable commodity (time), wouldn't not have been wasted. Thank you, I am subbing.

I think the only thing that this amazing video missed is to show why you connected each LED pole to resistor 1 and resistor 2. Thank you for sharing!

Doesn't adding the LED affect the voltage drop, since it also has a resistance? I wish you would have shown that.

Very good application of your voltage divider video. Keep the good work!

good but the arrangement of resistors made it complex and hard to grasp also you connected the circuit at the end without explaining the flow of the circuit. your slow paced explanation is excellent but you have to cover all bits and pieces to be crystal clear thank you

What are some applications of voltage dividers The video discusses how to build a voltage divider circuit to reduce the voltage supplied by a power source to a desired level. However, it doesn't go into the applications of voltage dividers. Finally, thank you for making this video!

This was super helpful, thank you sir

Thanks for sharing. we needed a simple divider circuit for an outside solar garden light. We have a LiOn 3.7VdC battery and need half that to drive the lighting circuit

Actually, I have to say thank you, because you help me with my physics with your invaluable videos. THANK YOU from the bottom of my heart.

What about the resistance of the LED? Doesn't that change the resistance of the circuit and change the voltage across it?

Hello! this video really helped me a lot but recently i was trying to create a voltage divider and selector circuit where we can control the voltage output of a circuit like for a 10v source we want the out to be 10v, 5V and later on 3 V how to achieve that?

aha, got it now, thanks, still dont understand why you wouldn't use a single resistor with a higher power rating to achieve the same effect?

Thank You! Sir... HelpFull.

thanx very much .. all the best

It is posible doing a voltage divider with a maxximum of 0-150v DC input 0-60A. If any resistor could get this amount of current. Voltage regulartor is not a good way for me because I am looking a variable output voltage depending from the input voltage. Thanks for help

how to calculate max load for such ?

Thank you so much

Finally I get it! Now I feel like a moron for not understanding before

thank you .1 watt resister on breadboard,

Thanks ❤

*NEVER use low value resistors for voltage dividers unless you **_KNOW_** the power usage.* To light up a resistor, multiply all the values by 100-1k ohms.

i have sensor operate 18-30v and i want connect to arduino esp32 and get value from arduino esp32 that operate voltage is 3.3V.. can u recommend how wiring and resistor value that can i use.. TQan i use.. TQ

very nice video

could someone apply this circuit on protues

Awesome...

Thank you.

how the led feed with 200mA without resistance ....by divide 3 volt/15 =200mA

Good

The camera wobbling is a problem for my brain, because of brain problems

So the voltage that goes to the LED is 3 volts?

The resistor got too hot

Looks like you forgot to show on the multimeter the amount of current running through the LED

Thank you so much

I did same with battery charger which ended with heat and smoke

10 ohm resistor.... Erm.... 10 ohm melts.... Do you mean 10k resistor for R1 ?

Make an other circuit using one transistor to make telephone ringer

reason why in this video he uses 2 resistor is that is the voltage divider rules..minimum 2 resistor..more than that its fine, less than that IT WONT WORK..that what ive been thought in school.

You don't need a voltage divider. You're just wasting current that way.

çok iyi.

Thank you!

I'm not sure about the "no one can put it simpler than this." If that's the case, then there is no hope of me ever learning what the purpose of a voltage divider is for. Why would you use two resistors to divide the voltage instead of using a single resistor with a higher rating? I want to learn how to measure analog inputs with an Arduino. It's my understanding I must use a voltage divider for input into the ADC but I have no idea WHY. Why not a single resistor with a higher rating? I cannot find this explained anywhere.

i want to use a fan which is rated at 12volts and 1.2 amps, but the power source i have is 24volts. will this method work to turn on the fan ? i guess the resistors would burn out as it cannot deliver 1.2amps ? please reply

Dont forget to highlight how much resistor wattage to use here . 1 watt resistor should work . however for the sake of understanding voltage divider this video have point ,but its not realy applicable in real life application since its not very efficient . and your led wont last that long.

this video shortly explain the whole concept and connection done in the experiment ...thank you ☺

How to reduce transformer out put voltage from 24 volt to 22 volt but not altering current???

comment

This video and your basics video gave a very nice description of voltage dividers.

Finally can probably make a parallel line for a low and a high beam for a one LED.

Thanks. Good tutor

Ur resistors are blue & not light brown, are they metal film resistors?. Are they 1/2w resistors?. Pls mention the resistor's value, tolerance, type & other details no matter how basic the video is.

I want to use 9 volt and 6 volt for 2 different things from a voltage source of 90 volts ! How to do this ?

This is so easy to understand

hello, why anyone the resistor is damage??

1-"The simply making" is not simple for students. 2-The electronic board without diagram is nothing. 3-at the end the multimeter obscure I see nothing. 4-repeat the video to yourself and see Finally excuse me
