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

Question

Quizplus · Accepted Answer

In a series RC circuit, the voltages across the resistor and capacitor are out of phase by 90 degrees. Therefore, the source voltage is the vector sum of the two voltages, calculated using the Pythagorean theorem: √(10^2 + 10^2) = 14.1 VRMS.
