For the given circuit of $P N$-junction diode, which of the following statement is correct
AIn forward biasing the voltage across $R$ is $V$
BIn forward biasing the voltage across $R$ is $2 V$
CIn reverse biasing the voltage across $R$ is $V$
DIn reverse biasing the voltage across $R$ is $2 V$

In an NPN transistor circuit, the collector current is $10 mA$. If $90 \%$ of the electrons emitted reach the collector, the emitter current ( $i$ ) and base current $(i)$ are given by
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
