SSA of RLC circuit

A series R-L-...

Question

A series R-L-C circuit is excited with a 50 V, 50 Hz sinusoidal source. The voltages across the resistance and the capacitance are shown in the figure. The voltage across the inductor $V_{L}$ is V.

50

Open in App

Solution

The correct option is A 50
$V = \sqrt{V_{R}^{2} + (V_{L} - V_{C})^{2}}$

$50 = \sqrt{50^{2} + (V_{L} - 50)^{2}}$

$V_{L} = 50$
