Capacitors - Technical MCQs

Q1:

What is the voltage across the capacitor?

A 7.07 V

B 1.11 V

C 111 mV

D 7.07 mV

ANS:C - 111 mV

The problem clearly states that the voltage drop on R is 7.072 V via the Voltmeter reading which means current flowing through the resistor would be 7.072mA and since it is a SERIES circuit current is the same for the resistor and capacitor, therefore, the VC = (7.072mA)(15.92ohms) = 112.6mV, 111mV is the closest.
