Beautiful explanation You could also find the voltage difference between the plates of 1st capacitor by creating a Kirchoff loop including 6ohm, 2ohm, and the 1st capacitor. Setting the eq. Vc-6*1-2*0=0 Therefore, Vc = 6V On the other hand, thank you for this nice video, sir!

Good morning sir, please help me understanding of total horizontal and vertical, RL parallel to capacitor?
ALAN GLODOWSKI without the LOAD, how much current in amps can a 4700uf hold store with a power supply DC voltage at +450vdc? the 4700uf filter cap will charge up to +450vdc but how much current is the 4700uf holding storing? What formula can I use to calculate how much current the filter cap is storing in amps?
@ChillPillDyl5 жыл бұрын
You need to trace across currents in the same direction for EVERY loop to prevent issues. If you trace clockwise in one loop, you need to trace clockwise for every loop. It just makes life easier and prevents errors.

@YouKnowMeDuh6 жыл бұрын
No, they act like shorts at t=0 and act like open circuits after a long time since no current can flow through them anymore. The current looks like exponential decay to zero at t>=0 when charging. Look up the graphs for this if you need a visual aid, it helps.

@joshuaronisjr7 жыл бұрын
Why does the current get split up that way? Since at the bottom junction there is no resistance between the battery on the left and the the junction, wouldn't all the electrons want to go there? Isn't it almost like a short circuit? (This question might make no sense). On a different note, can someone recommend another book besides the art of electronics for learning this? I find it really interesting, but I kinda wish it had more of the physics behind it to explain it. Also AOE is a great book, but its really dull looking, I think I'm mostly gonna use it to reference to things I don't understand. So yea, any suggestions? Thanks!

Only after ~5 effective time constants. Prior to this, current will be exponentially decaying in various loops while the capacitors are exponentially charging. Once the caps are charged (dV/dT ~0), then current is no longer flowing and Caps do indeed act like OCs. This is referred to as the "Transient Solution." and is usually not important other than to LEARN what is going on. AC Source designs seek to achieve the more important "Steady State" solutions. These topics are used to design filters (low pass, hi pass, band pass, notch, etc). But the systems can get so messy, that computer simulations (SPICE, MATLAB) and other freq response programs are used to evaluate the SS response.
