If $N_P$ and $N_e$ be the numbers of holes and conduction electrons in an extrinsic semiconductor, then
A$N_{P} ! N_e$
B$N_P \quad N_e$
C$N_P \sim N_e$
D$N_{P} ! N_e$ or $N_P \sim N_e$

In an experiment, the saturation in the plate current in a diode is observed at $240 V$. But a student still wants to increase the plate current. It can be done, if
A triode has a mutual conductance of $2 \times 10^{-3} mho$ and an amplification factor of $50.$ The anode is connected through a resistance of $25 \times 10^3$ ohms to a $250$ volts supply. The voltage gain of this amplifier is
