Full Wave Rectifier — Prelims Questions

A full-wave rectifier circuit uses two diodes. The input AC voltage is $V = 20 \sin(100\pi t),\text{V}$. If the diodes are ideal, what is the average (DC) output voltage across the load resistor?

A bridge rectifier circuit is supplied with an AC voltage of $220\,\text{V}$ (RMS) at $50\,\text{Hz}$ through a step-down transformer with a turns ratio of $10:1$. What is the Peak Inverse Voltage (PIV) that each diode must withstand?

Which of the following statements is INCORRECT regarding a full-wave rectifier?

In a full-wave rectifier, if the input AC frequency is $60\,\text{Hz}$, what is the ripple frequency of the output pulsating DC?

A full-wave rectifier has an input voltage $V_i = V_m \sin(\omega t)$. The average value of the output current through a load resistor $R_L$ is $I_{dc}$. If the diodes are ideal, what is the peak current ($I_m$) through the load?

A center-tapped full-wave rectifier uses two diodes. If the peak voltage across half of the secondary winding is $15\,\text{V}$, and the load resistance is $100,\Omega$, what is the approximate average DC current through the load? (Assume ideal diodes)
