Question

A common emitter transistor amplifier has a current gain of 50. The collector resistance is 5kohm and the input resistance is 1kohm calculate the output voltage if input voltage is 0.01v

Answer 1

Answer:

Given

β = Ic/IB = 50

Rc = 5k

Ri = 1k

Voltage output = βRc/Ri x voltage input

Voltage output = (50*5k/1k) x 0.01V

Voltage output = 250 x 0.01V = 2.5V
