In a full-wave rectifier circuit without a filter,the output current is

Write the principle of a rectifier.

$A$ full-wave rectifier circuit is operating from $50 \text{ Hz}$ mains. The fundamental frequency in the ripple output will be: (in $\text{ Hz}$)

$A$ diode detector is used to detect an amplitude modulated wave of $60\%$ modulation by using a condenser of capacity $250\, pF$ in parallel with a load resistance $100\, k\Omega$. Find the maximum modulated frequency which could be detected by it.

$A$ half-wave rectifier provides a load current of $1 \ k\Omega$. The input voltage is $220 \ V$. Neglecting the diode resistance,the values of average $DC$ voltage and average $DC$ current are respectively:

In a half-wave rectifier, an $AC$ input source of frequency $50 \,Hz$ is used. The fundamental frequency of the output is: (in $\,Hz$)
