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:

An ideal diode is connected in a circuit with resistance $R = 50\ \Omega$ and battery $V = 10\ V$ as shown in the figure. What are the maximum and minimum values of the output voltage when no load is applied?

In the circuit shown here, assuming the threshold voltage of the diode is negligibly small, the voltage $V_{A B}$ is correctly represented by which of the following graphs?

When $p$-type and $n$-type semiconductors are brought into contact,they form a $P-N$ junction which acts as a .........

If an alternating voltage is applied across a $p-n$ junction diode in series with a load,then:

How many junction diodes are used for half-wave and full-wave rectifiers,respectively?
