Question
A common emitter amplifier has a voltage gain of 50, an input impedence of 100Ω and an output impedence of 200Ω . The power gain of the amplifier is
Options
A.500
B.1000
C.1250
D.50
Solution
Here,
Voltage gain = 50
Input resistance, Ri = 100 Ω
Output resistance, R0 = 200 Ω
Resistance gain =
= 2
power gain =
= 1250.
Voltage gain = 50
Input resistance, Ri = 100 Ω
Output resistance, R0 = 200 Ω
Resistance gain =
= 2power gain =
= 1250.Create a free account to view solution
