Question
The input resistance of a silicon transistor is 100 Ω. Base current is changed by 40 mA, which resultsin a change in collector current by 2 mA. This transistor is used as a common emitter amplifier witha load resistance of 4 kΩ. The voltage gain of the amplifier is
Options
A.1000
B.2000
C.3000
D.4000
Solution
Ri = 100i
ᐃib = 40 × 10-6
ᐃic = 2 × 10-3
= 2 × 103 = 2000
ᐃib = 40 × 10-6
ᐃic = 2 × 10-3
= 2 × 103 = 2000Create a free account to view solution
