In the following circuit diagram, the current through the battery is

At a certain temperature, the number density of charge carriers in a semiconductor is $n$. When an electric field is applied to it, the charge carriers drift with an average speed $v$. If the temperature of the semiconductor is raised.

In the given circuit, The current through battery is

A common emitter amplifier has a voltage gain of $50$, an input impedance of $100 \mathrm{\Omega }$ and an output impedance of $200 \mathrm{\Omega }$. The power gain of the amplifier is
