When input voltage is $-10\ V$, the diode is reverse biased and no output is obtained. On the other hand, when input is $+10\ V ,$ the diode is forward biased and output is obtained which is $+10\ V.$ Therefore the output is of the form as show in the following figure.

In a semiconductor, the concentration of electrons is $8 \times 10^{14} / cm ^3$ and that of the holes is $5 \times 10^{12} cm ^3$. The semiconductor is
A $G e$ specimen is doped with $A l$. The concentration of acceptor atoms is $\sim 10^{-}$atoms $/ m$. Given that the intrinsic concentration of electron hole pairs is $\sim 10^{19} / m ^3$, the concentration of electrons in the specimen is
The amplification factor of a triode valve is $15.$ If the grid voltage is changed by $0.3$ volt the change in plate voltage in order to keep the plate current constant (in volt) is
