To solve the problem, we need to find the average power dissipated in a circuit consisting of a resistor and an inductor connected in series to an AC voltage source. Here are the steps to find the solution: ### Step 1: Identify the given values - Resistance (R) = 2 ohms - Inductive reactance (X_L) = 1 ohm - RMS voltage (V_rms) = 5 V ### Step 2: Calculate the impedance (Z) of the circuit ...
