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.

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.

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.

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

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

Is it 'music'? Music is always annoying and pointless in these otherwise brilliant and clear instructional videos - but this takes things to new heights! It's not music, just a pointless and annoying sound.

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?

I think he has a typo in his chart. He looks to be using a 100uF cap, but his chart says 0.0001uF, and it's actually 0.0001F

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.

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

A high resistance is used for two reasons. Firstly to make it easier for students to capture the charge curve and secondly to demonstrate the effect of the input impedance of the scope when it is used to take measurements from circuits which contain high resistances such as this one :)

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 ;)

You have to be careful with the voltage with ac ( well dc as well) and make sure the capacitor rating is around 2 x higher than the peak ac voltage. This test is specifically for dc.

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.

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.
