$A$ full wave rectifier circuit consists of two $p-n$ junction diodes,a centre-tapped transformer,a capacitor,and a load resistance. Which of these components removes the $AC$ ripple from the rectified output?

Constant $DC$ voltage is required from a variable $AC$ voltage. Which of the following is the correct order of operation?

$A$ $p-n$ junction diode $(D)$ shown in the figure can act as a rectifier. An alternating current source $(V)$ is connected in the circuit. The current $(I)$ in the resistor $(R)$ can be shown by:

What is rectification and rectifier? Why is a $p-n$ junction diode used as a rectifier?

In a half-wave rectifier using a $PN$ junction diode,the input voltage has an amplitude of $25 \ V$ and a frequency of $50 \ Hz$. No filter is used,and the load resistance is $1000 \ \Omega$. The forward resistance of the diode is $10 \ \Omega$. The $d.c.$ power output and $a.c.$ power input are respectively:

The frequency of a given $AC$ signal is $N \ Hz$. When it is connected to a half-wave rectifier,the number of output pulses given by the rectifier in $1 \ s$ is:
