Q. Let $i_{e},i_{c}\ and\ i_{b}$ represent emitter current, collector current and the base current of a transistor, then
A) $i_{c} > i_{e}$
B) $i_{b} > i_{c}$
C) $i_{b} > i_{c}$
D) $i_{e} > i_{c}$
Explanation
(d) For transistor $i_{e} = i_{c} + i_{b}$
$i_{c} = 95\%\ of\ i_{e}$
$i_{b} = 5\%\ of\ i_{e}$
So, $i_{e} > i_{c}$
