Diode as Rectifier — MCQ Practice

A half-wave rectifier circuit uses a diode with a forward resistance of $10,Omega$ and a reverse resistance of infinity. The input AC voltage is $V = 100 sin(314t),\text{V}$ and the load resistance is $R_L = 990,Omega$. What is the average DC current in the circuit?

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

A full-wave rectifier circuit delivers a DC output voltage of $10,\text{V}$ to a load resistor of $100,Omega$. If the peak voltage across the secondary winding of the transformer is $V_m$, what is the approximate value of $V_m$ for a bridge rectifier?

A rectifier circuit has an input AC frequency of $50,\text{Hz}$. What is the ripple frequency of the output for a half-wave rectifier and a full-wave rectifier, respectively?
