In the case of $NPN$ transistors,the collector current is always less than the emitter current because:
- ACollector side is reverse biased and emitter side is forward biased
- BAfter electrons are lost in the base,only the remaining ones reach the collector
- CCollector side is forward biased and emitter side is reverse biased
- DCollector being reverse biased attracts fewer electrons

In a $CE$ transistor, a change of $8.0 \,mA$ in the emitter current produces a change of $7.8 \,mA$ in the collector current. What change in the base current is necessary to produce the same change in the collector current (in $\mu A$)?
For a common base transistor,the current gain is $\alpha = 0.98$. To produce a change of $2 \ mA$ in the emitter current,the change in the base current must be ......... $mA$.
