In a series RC circuit, the resistor voltage is 124 V and the capacitor voltage is 167 V. What is the total voltage?
A) 111 V
B) 143 V
C) 208 V
D) 240 V

Question

Quizplus · Accepted Answer

The total voltage in a series RC circuit is found by the square root of the sum of the squares of the resistor voltage and the capacitor voltage: $V_{total} = \sqrt{V_R^2 + V_C^2} = \sqrt{124^2 + 167^2} = \sqrt{15376 + 27889} = \sqrt{43265} \approx 208 V.$
