In the circuit of the figure below, script e = 2.0 kV, C = 7.0 µF, R1 = R2 = R3 = 0.61 MΩ. With C completely uncharged, switch S is suddenly closed (at t = 0).
(a) At t = 0, what is current i1 in resistor 1?
(b) At t = 0, what is current i2 in resistor 2?
(c) At t = 0, what is current i3 in resistor 3?
Repeat for t = infinity (that is, after many time constants.)
(d) What is current i1?
(e) What is current i2?
(f) What is current i3?
(g) What is the potential difference V2 across resistor 2 at t = 0?
(h) What is V2 at t = infinity?
RC Circuit: q=q0[1-e^-t/(RC)]-Charge in capacitor.
Discharge of Capacitor-q=q0e^-t/(RC)
The Attempt at a Solution
I've been trying this for days and have a test on it tomorrow. I have the faintest idea where to start. Thanks for the help in advance, I need it badly.
