(C) The peak current $I_m$ is given by $I_m = \frac{V_m}{R_f + R_L} = \frac{25}{10 + 1000} = \frac{25}{1010} \approx 0.02475 \ A = 24.75 \ mA$.The $DC$ current $I_{dc}$ is $I_{dc} = \frac{I_m}{\pi} = \frac{24.75}{\pi} \approx 7.88 \ mA$.The $RMS$ current $I_{rms}$ for a half-wave rectifier is $I_{rms} = \frac{I_m}{2} = \frac{24.75}{2} = 12.375 \ mA$.The ripple factor $\gamma$ is defined as $\gamma = \sqrt{\left( \frac{I_{rms}}{I_{dc}} \right)^2 - 1}$.Substituting the values: $\gamma = \sqrt{\left( \frac{12.375}{7.88} \right)^2 - 1} = \sqrt{(1.57)^2 - 1} = \sqrt{2.46 - 1} = \sqrt{1.46} \approx 1.21$.
