In common emitter amplifier, input resistance is 1000 , peak value of input signal voltage is 5 mV and =60 . The peak value of output current is
Options
- A0.5 10⁻⁴ ~A
- B3 10⁻⁴ ~A
- C2 10⁻⁵ ~A
- D1 10⁻⁵ ~A
Correct answer
B. 3 10⁻⁴ ~A
Step-by-step solution
r_ L =1000 _ i =5 mV =5 10⁻³ ~V =60I_ input = 5 10⁻³ 1000 =5 10⁻⁶ ~A I_ output =60 5 10⁻⁶ ~A =300 10⁻⁶ ~A =3 10⁻⁴ ~A
