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
When the $P$ end of $P-N$ junction is connected to the negative terminal of the battery and the $N$ end to the positive terminal of the battery, then the $P-N$ junction behaves like
The grid voltage of any triode valve is changed from $-1$ volt to $-3$ volt and the mutual conductance is $3 \times 10^{-4} mho$. The change in plate circuit current will be
