1. ### A doubt about RC circuits

yes...this is what i was asking. What exactly do we mean by displacement current and in Which direction would the displacement current flow?
2. ### A doubt about RC circuits

Thank you for all the help :) Ok I was actually working on this question (attached below) We have to find the current through the resistor R11 after the switch is opened. ( it was shut for a long time prior to it opening at t=0) Everything is correct but my final answer is wrong...
3. ### A doubt about RC circuits

http://apricot.polyu.edu.hk/~lam/cp/img/rc-circuit.gif" [Broken] Uhh...so what you are saying is the current goes from the +Vc towards +Vb in anti clockwise direction? But it wont go from +Vc to -Vc to -Vb to +Vb and so on in a clockwise direction?
4. ### A doubt about RC circuits

Happy new year too you too :) What did u mean by currents have to go the long way around? Anyway eventually i agree that there will be no current across a capacitor. But what about while its charging? there will be voltage across it, and shouldnt that mean a current also flows?
5. ### A doubt about RC circuits

In an RC circuit shown below, with the switch closed after a long time, when the capacitor is charging, there is a current across the capacitor given by Initial current x e ^ (-t/RC)... Is this current....the current supplied by capacitor to the rest of circuit, or simply the current across...
6. ### Two Parallel Voltage sources and KVL

Hi, I understand that you cannot apply KVL to voltage sources connected in parallel, unless both voltage sources are the same, as this violates KVL. However, I want to know why? Just a simple 2-3 line explanation will suffice. Regards
