Question
In n-p-n transistor circuit the collector current is 10mA. If 90% of the election reach the collector, then emitter current will be
Options
A.1 mA
B.0.1 mA
C.2 mA
D.nearly 11 mA
Solution
Ic = 10 mA ; Ic + Ib
If Ic = 90% of Ie,
then Ic =
× Ie
⇒ Ie =
Ic
If Ic = 90% of Ie,
then Ic =
× Ie ⇒ Ie =
