Caveman Al Toraboran:3:25 freaking video finally starts here.
Caveman Al Toraboran: Dude you talk too much freaks sake. Great video otherwise.
marc wischkaemper: Very nice tutorial. Mad scope skills!
Jay Yang: jay yang
Popart 2015: The problem is that water is used as analogy to electricity instead of gas, because water is practically incompressible contrary to gas. A capacitor should bee seen as a gas cylinder instead of a bucket. This way you may do a better analogy, like this:
V = Gas pressure; Q = Gas quantity; C = Capacity of Gas storage for a given pressure, and so Q/V.
Like a gas cylinder, greater pressure (V) means that greater quantity (Q) may be stored, however, if you increase V (gas pressure) too much, it blows up, so, besides C a capacitor has also defined the maximum pressure V it can handle before it blows up... This is why you should think in electricity as Gas flow instead of Water flow.
LM: Great job Martin! thank you so much for explaining this very important concept. I like the way you go, explain the concept first then go to real world example, better yet, step by step. It is nice too that you along the way make mistakes and comment on that later so we can learn from that too. Way to go! keep up with the good work!
Dog Rox: Thomas Cain have you figured out how to get the average on your siglent scope?
Leonard Legg: One probably needs to know that T does not stand for time (persay) It is a greek symbol called tau. It is derived from RC and it takes 10 tau for a capacitor to fully charge. But a capacitor charges to 63.2% of the total charge voltage in 1 tau. That gives you a rule to work with for this calculation. So in this operation you are measuring tau (in time)on the scope and using that figure to calculate C. Just sayin.
Haroon Christopher: Do you have a video on VI characteristics of diode on Oscilloscope and rectification verification of bridge circuits on oscilloscope, kindly send its url.
Dog Rox: Hi, I have a question now that I've been trying to play with that on my scope, I have an SDS 1000 series scope from Siglent and is one thing I can't figure out how to do yet, is to get both the X cursors and the Y cursors on the screen at the same time. Yes I am very new to oscilloscopes, I'm learning as I go along. It seems I can only get either the X or the Y on the screen but never both the same time. Am I missing something or is this one of the features lacking in this particular scope?
Donald McVey: Very methodical procedure and therefor a very good tutorial. I appreciated and enjoyed watching!
Tommy N: Great video! Thanks!
Dog Rox: I know this is an old video but I found it very educational. I really appreciate this video. Also I read what Andre said in his comment. That does make a lot of sense what he said. But still I did learn quite a lot of this video I'm going to experiment with that myself. thanks for the tutorial. :-)
Chris Kreitlein: I am a beginner with the oscilloscope ... and I am a teacher (both high school and adults at night school). Your delivery and explanations are outstanding. I rarely see an instructor deliver the sort of simple detail that a beginner needs....but you, my friend, did. Thank you and congrats.
Digger D: I'm cutting your film budget in half ;) Now you will have to do your videos in half the time. But well done anyway.
Digger D: I find large discrepancies between an LCR meter and a DMM on electrolytic capacitors and will use this method to check and see which is closer - of course frequency comes into play. Have you noticed this? Measure on DMM and then LCR and compare results. Again only on electrolytic types for the most part.
robertpk: @mjlorton, on the background, I see that you have a AIM-TTI generator, why did you choose it over for example Rigol series?
lnpilot: So: get a $2000 oscilloscope and a $500 function generator and fiddle 10 minutes to measure each capacitor with crappy accuracy vs. getting a $200 LCR meter and spending 2 seconds per capacitor and getting accurate measurements...
Charlie Anstedt: what is the racetrack on the side of the cap,?
