In an $n-p-n$ transistor, the collector current is $10 \mathrm{~mA}$, if $90 \%$ of the electrons emitted reach the collector, the emitter current $\left(I_{E}\right)$ and base current $\left(I_{B}\right)$ are given by (a) $I_{E}=-1 \mathrm{~mA}, I_{b}=9 \mathrm{~mA}$ (b) $I_{E}=9 \mathrm{~mA}, I_{B}=-1 \mathrm{~mA}$ (c) $l_{E}=1 \mathrm{~mA}, l_{B}=11 \mathrm{~mA}$ (d) $I_{E}=11 \mathrm{~mA}, I_{B}=1 \mathrm{~mA}$

Round 1
In NPN transistor the collector current is $10 \mathrm{~mA}$. If $90 \%$ of electrons emitted reach the collector, then (A) emitter current will be $9 \mathrm{~mA}$. (B) emitter current will be $11.1 \mathrm{~mA}$. (C) base current will be $0.1 \mathrm{~mA}$. (D) base current will be $0.01 \mathrm{~mA}$.
