Silicon is a semiconductor. If a small amount of As is added to it, then its electrical conductivity

In the energy band diagram of material shown in figure open circles and filled circles denotes holes and electrons respectively. The material is

Consider the junction diode is ideal. The value of current through the resistance of $300 \mathrm{\Omega }$ is

In a $p-n$junction the depletion layer of thickness ${10}^{-6} \mathrm{m}$ has potential across it is $0.1 \mathrm{V}$. The electric field is $\left(\mathrm{V} {\mathrm{m}}^{-1}\right)$

A common emitter amplifier gives an output of $3 \mathrm{V}$ for an input of $0.01 \mathrm{V}.$ If the current gain of the transistor is $100$ and the input resistance is $1 \mathrm{k\Omega }$, then the collector resistance is

The circuit is equivalent to
