In an RC parallel circuit, E_T = 120 V, R = 420 Ω , and X_C = 330 Ω . What is Z? A) 140 Ω B) 230 Ω C) 259.62 Ω D) 534.13 Ω

Question

Quizplus · Accepted Answer

The total impedance (Z) in an RC parallel circuit is found using the formula $Z = \sqrt{R^2 + (X_C)^2}$, where $R$ is the resistance and $X_C$ is the capacitive reactance. Plugging in the given values, $Z = \sqrt{420^2 + 330^2} = \sqrt{176400 + 108900} = \sqrt{285300} ≈ 259.62 \Omega$.
