Solved Examples of Power Amplifier
There are some Solved Examples of Power Amplifier given below :
1. Calculate the efficiency of a Class A power amplifier with an output power of 10 watts and a DC power input of 20 watts.
Solution:
[Tex]Efficiency = \frac{Output Power }{ DC Input Power}*100% [/Tex]
[Tex]Efficiency = \frac{10}{ 20}*100 = 50% [/Tex]
2. Determine the gain of a transformer-coupled Class A amplifier with a turns ratio of 1:5.
Solution:
[Tex]Gain = \frac{Number of Turns in Secondary}{Number of Turns in Primary} [/Tex]
Gain = 5
