If there is 10 V_RMS across the resistor and 10V_RMS across the capacitor in a series RC circuit, then the source voltage equals A) 14.1 V_RMS B) 28.3 V_RMS C) 20 V_RMS D) 10 V_RMS

Question

Quizplus · Accepted Answer

In a series RC circuit, the voltages across the resistor and capacitor are perpendicular to each other in the complex plane. To find the total voltage, you use the Pythagorean theorem. Since both the resistor and capacitor have 10V across them, the source voltage is the square root of (10^2 + 10^2) = sqrt(200) = 14.1V.
