Normally,a capacitor is connected across the output terminals of a rectifier to

The output current versus time curve of a rectifier is shown in the figure. The average value of output current in this case is

$A$ full-wave rectifier with diodes $D_1$ and $D_2$ is used to rectify $50 \,Hz$ alternating voltage. The diode $D_1$ conducts .......... times in one second.

Which is the correct diagram of a half-wave rectifier?

The peak voltage in the output of a half-wave diode rectifier fed with a sinusoidal signal without a filter is $10 \ V$. The $dc$ component of the output voltage is:

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:
