Quizplus · Accepted Answer

The DC current in a half-wave rectifier is given by the average value of the rectified output, which is $I_{DC} = \frac{V_m}{\pi(R_F + R_L)}$, where $V_m$ is the peak voltage, $R_F$ is the forward resistance of the diode, and $R_L$ is the load resistance. The correct formula takes into account both the forward resistance of the diode and the load resistance, which are in series in the circuit.
