Q. What is an amplifier? What are the various types of amplifiers?

AMPLIFIER: A circuit that increases the amplitude of the given input signal is an amplifier. A small a.c. signal fed to the amplifier is obtained as a larger a.c. signal of the same frequency at the output. They constitute the essential parts of many communication circuits such as television and radio.
