Trivia Quiz On Amplifier In Electronics Engineering

Let’s start the quiz

An amplifier is a device that is used to increase the voltage and current of a signal. Simply put, the amplifier increases signal strength. It converts a weak electrical signal into a strong signal. The amplifier is a two-port electronic circuit that uses electric power to increase the amplitude of the signal located at the input terminals and thereby gives us more output A larger amplitude signal is obtained. Let's know more about Amplifier In Electronics Engineering.
