The $PN$ junction diode is used as:

$A$ $p-n$ junction diode as a rectifier converts

Which of the following figures represents 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:

If a centre-tap transformer is used with two $p-n$ junction diodes for full-wave rectification,then the output voltage of the rectifier with respect to each diode is (secondary voltage of transformer $= V_s$)

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:
