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. |
