$A$ crystal diode is a:

The value of net resistance of the network as shown in the given figure is:

If in a $p-n$ junction diode,a square input signal of $10\, V$ (varying from $+5\, V$ to $-5\, V$) is applied as shown,then the output signal across $R_L$ will be:

In a semiconductor $p-n$ diode, the doping concentrations on $p$-side and $n$-side are $10^{15} \text{ atoms/cm}^3$ and $10^{18} \text{ atoms/cm}^3$, respectively. Which one of the following statements is true?

When a $P-N$ junction is in reverse bias,the current flowing through the junction is primarily due to:

When a forward bias is applied to a $p-n$ junction, it . . . . . . .
