Quizplus · Accepted Answer

In a series RC circuit, the impedance (Z) is the combination of resistance (R) and reactance (Xc) due to the capacitor, calculated using the formula Z = sqrt(R^2 + Xc^2). This means the impedance is always larger than the resistance alone, as it combines both resistive and capacitive properties.
