How do you amplify power?
Answers
A very common method of amplifying power output in projects is with transistors. The term “transistor” is short for “transconductance varistor,” which means that it is an electrically controlled variable resistor.
Answer:
An amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the power of a signal (a time-varying voltage or current). ... The amount of amplification provided by an amplifier is measured by its gain: the ratio of output voltage, current, or power to input.
Explanation:
The power amplifier works on the basic principle of converting the DC power drawn from the power supply into an AC voltage signal delivered to the load. Although the amplification is high the efficiency of the conversion from the DC power supply input to the AC voltage signal output is usually poor.
