Distinguish, differentiate, compare and explain what is the main difference between Voltage and Power Amplifier.

Difference between Voltage and Power amplifier

S.No. Voltage Amplifier Power Amplifier
1 Transistor chosen should have a high value of beta about 100. Transistor should have a small value of beta about 20 to 50.
2 The load resistance Rc has a high value about a 1OK ohm. The load has a small value of 100 to 200 ohm.
3 An input voltage is low approx a few mV. An input voltage is high about a few volts.
4 Has a low power output and high voltage output. Has a high power output and a low voltage output.
5 Collector current has low-value 100mA. Collector current has a high value in power amplifier.
6 Output impedance has a high value. Output impedance has low value.
7 Usually, R-C coupling is used. Transformer or tuned circuit is always used.
