Question

(a) What is the maximum value of the current in the circuit?
1 A

(b) What are the maximum values of the potential difference across the resistor and the capacitor?
VR,max = 2 V
VC,max = 3 V

(c) When the current is zero, what are the magnitudes of the potential difference across the resistor, the capacitor, and the AC source?
VR = 4 V
VC = 5 V
Vsource = 6 V
How much charge is on the capacitor at this instant?
qc = 7 µC

(d) When the current is at a maximum, what are the magnitudes of the potential differences across the resistor, the capacitor, and the AC source?
VR = 8 V
VC = 9 V
Vsource = 10 V
How much charge is on the capacitor at this instant?
qc = 11 µC

Explanation / Answer

a)Imax = V/R = 172/(1.1*1000) =0.156 A

B) VR,max = 172 V

VC,max = 172 V

C) when I = 0 A

VR = 0 V

VC = 172 V

VSource = 172 V

qC = C*V = 2.5*10^-6*172 = 0.00043 C = 0.43 mC = 430 uC

d) VR = 172 V

VC = 0 V

VSource = 172 V

qC = 0 uC
