Question
**Question:** The power output of the half-wave rectifier is rated at 102.4 W with a load resistor of 40 ohms. The RMS voltage at the output is: - A. None of the other choices are correct - B. 12.5 V - C. 102 V - D. 25.5 V - E. 51 V **Explanation:** To find the RMS voltage at the output, we use the formula for power: \[ P = \frac{V^2}{R} \] Where: - \( P \) is the power (102.4 W) - \( V \) is the RMS voltage - \( R \) is the resistance (40 ohms) Rearranging to find \( V \): \[ V^2 = P \times R \] \[ V = \sqrt{P \times R} \] \[ V = \sqrt{102.4 \times 40} \] Calculate the result to determine the correct choice for the RMS voltage.
