In a common emitter transistor amplifier an increase of 50 μA in the base current causes an increase of 1 mA in the collector current. The change in emitter current is
A
1050 mA
B
1050 μA
C
5025 mA
D
5025 μA
Answer
1050 μA
Explanation
Solution
: the change in emitter current is
ΔIE=ΔIB+ΔIC
=50×10−6+1×10−3
1050×10−6A=1050μA
