For R = 1000 W, C = 2000 mF, Qo= 20 mC.
(a)How long will it take before the capacitor discharges to Qo/100.
(b)What is the value of current at t = 4 sec.
I am completely lost on how to solve this question, please can anyone give me help in the right direction. Thanks in advance!
Do you read your text? Do you go to class and take notes? I am fairly certain you are not so helpless. Look in your text under RC decay.
I will be happy to critique your thinking, but honestly, I think you are answer grazing. This relation in RC circuits is pretty basic.
