Arnold Scwartzenager said “ any rep is a hood rep”… THIS LECTURE IS…DELICIOUS…. In high school I attended “Vocational Training” / electronics in my junior and senior years… ( 1972-1974)… and resistors, capacitors and inductors… and therefore LRC circuits …and therefore “ right triangles”…. Were…the…. Peak of our mountain tops…. I am interested in reviewing the concepts … just because…. ( and I have some old tube and transistor amps)… I can clean pots, switches and tube sockets all day… but eventually we need to remember how to trace volts … know what to expect …and how to do it safely when sometimes there is 400 volts in the circuit. Again… GREAT…SERIES…of lectures… ( one of my first benchmarks when I saw that I was from a previous generation…. My younger ( by eight years) sister… while holding my slide rule…I asked… “how do you use this?”…. And then my even younger sister ( ten years).. asked.. “ what …IS…this thing?”
Ok so.. ive gone from kind of knowing, to knowing nothing... several times during this. Do i stop or continue? All i want to do is switch this GD mosfet and im mixed up to heck with what resistance after R has raised and lowered v and i at each turn :(
It was 0V across the discharged capacitor (acting like a pice of wire at the beginning), but there was 1V across the resistor - the only one element limiting the current - that's why 1 amp of current. And that's why you shouldn't connect (especially big) capacitor directly to the power source.
Hi bob...something is confusing here, i belive you are refering to a non polar capacitor here.in your video about voltage amplifier (using a microphone as Ac source ) you use a capacitor to block Dc.i guess a polarised capacitor is what you where refering to at that time. Am i correct in my understanding?if not, hence does a non polar also blocks Ac ?
Perfect explanation without bring ODEs into the discussions.I was always struggling a bit with this concept. Thank you heaps!
Wow. Simply wow.
Very good explanation 🌅🌅
Simply great
No words to express
you have no idea how much this has helped me, thanks!!!
Only explanation that didn't leave me more confused
Best electricity lecure I've ever seen.
Very helpful. Cleared up the confusion I had from my textbooks!
Sir. You are the best teacher of electronics on the internet. Thank you!

Ooops…”any rep… is a GOOD rep”… this lecture is re- pushing my brain… and it hurts good.
Slide rules and Trig… we didn’t have “useless numbers”… we had “one more step” … and all answers needed to be out to the .oox .. using the slide rule.
Finally a great explanation after years of kinda knowing
Thanks 😊👍🙏💯
Crystal clear board work, awesome...
Brilliant lecture Sir
Outstanding explanation
Very good Bob. A lot of detail crammed into this 36 minutes, very well explained.
Very important info...Thanks, Bob!
thank you so much for this wonderful video.
I was lost. I looked for Big Bob. I found him. He found me. There for, I was found. Thank you Big Bob
Fantastic explainer, thanks very much
Simply brilliant. Thank you Sir.
really great video

really truelly great explanation
Current does NOT flow through a capacitor, just in and out of it. He explains this in the beginning.

This topic is pretty hard. What about this video do you not understand. I'll try to explain
@@Slovenija_patriot Confused whether more or less resistance raises or lowers current and voltage on the gate.
How can you have 1 amp of current flow with 0 volts?

By the way great exaplation
