In a common emitter transistor amplifier the audio signal voltage across the collector is `3 V`. The resistance of collector is `3 kOmega`. If current gain is `100` and the base resistance is `2 kOmega`, the voltage and power gain of the amlifier is :

Options

A. 200 and 1000
B. 15 and 200
C. 150 and 15000
D. 20 and 2000

Explanation

Given that the current gain for the common emitter transistor amplifier `beta= 100`
Resistance gain `(R_(C))/( R_(g)) = (3)/(2)`
Power = Voltage gain `(Ap) xx ` current gain `(beta)`
Power gain `= A_(v) zeta = 150 (100) =15,000`
