The width of forbidden gap in silicon crystal is $1.1\ eV$. When the crystal is converted in to a $N$-type semiconductor the distance of Fermi level from conduction band is
For a transistor, the current amplification factor is $0.8.$ The transistor is connected in common emitter configuration. The change in the collector current when the base current changes by 6 $m A$ is
For a triode, at $V_g=-1$ volt, the following observations were taken $V_p=75 V , I_p=2 mA , V_p=100 V , I_p=4 mA$. The value of plate resistance will be
