Oscilloscope Measure Voltage across a Charging Capacitor 

Most informative! Your 10 yr old video provided more insight on how to use an oscilloscope than the dozens of recently posted videos that I have watched!

Thank you for the demonstration. The "micro" should be erased in "0.0001 uF," because 100 micro Farads converts to .0001 Farads. When the number of the quantity decreases during a conversion, the size of the unit of measure increases to compensate.

Good to see the beetles are constructive in there retirement

Thank you so much for this life-saver tutorial! It is short but very informative! Thank you for sharing this!

Fantastic illustration and a very clear video and explanation. Thanks!!

Great video! I came here just to see how to set the scope settings, but I learned a bit more. No matter how much I use my scope, I'm still learning about a scope's capabilites. Thanks! And not to mention that your explanations are easy to understand...at least to me anyways. I will be subbing to your channel.

Great video. I set up the experiment and watched the results on my own 'scope. Thank you.

video is fantastic, thank you for posting

Hi Paul, I love your videos on using an oscilloscope because I was scammed out of €46,000 by a Romanian lady who when had all the money I could give her wanted nothing to do with me, now I need to try and make that money back but I need to learn electronics as I have a scope and a power supply and signal generator, I now need to learn more about electronics and I find your videos very helpful, wonderful work so I wish you the best of everything always.

Good job. Looking for more of your videos.

Fantastic, Thanks for your time and knowledge. I'm a weekend electronics, slash, Arduino guy. I just bought a scope and I'm looking for ways to use it. Thanks again.

this was a very great video, thank you ))

Thanks a lot for sharing, this was great! :-)

tnx .It's interesting one .Just go on like this even ur expression is clear & precise ever

I love u already thank u for ur demonstration!

excellent video my good man. Thank you

Thank you sir. This was very helpful.

Excellent tutorial...can we also measure high voltage loading and unloading curves to check if the input voltage is exactly what it displays on the screen.

A great help thank you.

Great video as always Paul. I fear our older analogue scopes don't have these cursors though, so we will just have to count squares !

Hi Paul, I came across your video and could you tell me have you any others on the Oscilloscope, if so could you put some more on. thanks lou

excellent tutorial.....I find the background music distracting though.

Great explanation, thanks. But please without background music

I happen to like the background music as long as it doesn't overload everything. What is the name/artist of the song?

Thanks dude..it helped me.

Great video thanks

Greattt, Very Practical

Does this work with a breadboard and a 5 volt dc power supply? I can't seem to get it to work. I put a resistor and capacitor in series but it doesn't show the rise on the oscilloscope. Just a steady DC line

Thanks for explanation, I'm currently learning electronics, and just found out about your channel, I am looking at Owon PDS5022T to buy, I want it to assist me to learn electronic circuits, and visualize waveforms. also to compare a wave, vs a distorted wave for instance. Do you know what are the differences between it and yours ? I'm working with audio circuits, and this is the direction I want to take, and also visualize waveforms from audio/LFO, Envelope generators

What kind of oscilloscope should I use to capture very short capacitor discharges, few µs?

PAUL WESLEY LEWIS, what is the difference between joules to wattage or are they the same thing. What circuits would i want to measure joules? Joules is based on seconds time but its the wattage of a circuit

good job

Perfect Exponation. Music ok

Curser readings represents delta?

What was that capacitor measurement, a 100MFD???

In which country is this college is and if I wanna do my registration how it going to be as a foreign student answer plz

What is the rise time of your power supply from 0 to 5v ?

nice

Loved it. But Mi would have turned the Power supply before, inserting a normal switch. Because then then the power supply is fully operational then. Just flick the switch and you might get a more precise reading. Just a guess

hi which the valus of time/div ?

How did you know it takes 5 time constants to fully charge?

Sir can you make us more videos about oscilloscope

Sir how to measures ESR using ossiloscope

how can you measure voltage and current of rlc circuit with osciloscop?

Why oh why is it necessary to have annoying music in the background. ? I cannot be the only one that finds background music distracting . Other t Han that, very useful information. Thanks for your efforts.

0.0001uF is 0.1nF which is 1x10^(-10). If I multiply 1x10^(-10) by 1x10^5 I get 100ms. How does that gave you 10 seconds of time constant?

At 2:10 your equation says 0.0001uF*100000Ohm=10sec which is wrong. I think you meant 0.0001F not uF which is exactly what you've actually said at 2:30.

how to saving to flash disk

Is that mesure wiring method safe to use with a AC source?

Not so sure about scope resistance being the cause of voltage stopping at 4.5V. We have a voltage divider here. 100K resistor plus 10M scope (probe) internal resistance. Vscope=5V * (100K+10M)/10M = 4.95 V. More likely it is your power supply not really outputting what the readout says. My cheapo Chinese supply at least has two dials (coarse and fine) for V and two more for A and it still is off. Yours only has one dial each. Don't tell me it's actually calibrated to x decimal places ;)

Arduino 5v pushing too much current as it charges the cap in uSeconds., added a 1M in series with the 100k resistor. 2.84v at 63.2%, tau = 84sec divided by 1.1Mohm is 76uF for a 100uF cap... Math doesn't work out; but, at least the culprit "current" was identified! RIGOL DS1052E horizontal time scale at 50 seconds and you have to wait 3 mins before the graph appears! patience grasshopper.

Why is the current on the power supply set to zero?

Nicely explained. Really. But if you had used a lower value resistor you wouldn't have loaded down your circuit that much.

After ten time constant’s worth of time, the percentage is 99.995. So not 5 times.

IS it possible to achieve degradation with this approach?

Very nice music but your lesson was distracting

If the point of the video is to teach something the distracting beat of your annoying music defeats your intended purpose. This is why so many inventors today don't come up with anything because there is always some damn distraction in the background which interrupts the line of thought. Can you focus on one problem fro 37 minutes without having any thoughts about anything else in that time? Albert Einstein did that. SO did the great Nikola Tesla. Focus. No distractions.

Please don't use music or drums in the background, makes it difficult to co hear and concentrate on what is being said.
