A series RC circuit contains two resistors and two capacitors. The resistors are 39 Ω and 68 Ω . The capacitors have capacitive reactances of 60 Ω and 50 Ω . The applied voltage is 240 V. What is the voltage drop on the capacitor that has 50 Ω of reactance?
A) 93.84 V
B) 106.35 V
C) 178.2 V
D) 260.99 V

Question

Quizplus · Accepted Answer

The voltage drop across a capacitor in a series RC circuit can be found using the formula Vc = (Xc / Z) * V, where Xc is the capacitive reactance, Z is the total impedance, and V is the applied voltage. Calculate Z using the resistors and capacitors, then find the voltage drop across the 50 Ω capacitor.
