Question

What does a transistor amplify?

Answer 1

1. A transistor is a semiconductor device that can conduct as well as insulate electrical current or voltage.
2. A transistor is a switch and an amplifier in one. A transistor, in simple terms, is a small device that is used to control or regulate the flow of electronic impulses.
3. Transistors can act as amplifiers while they are functioning in the active region or when it is correctly biased.
   
4. The CE configuration for transistors as amplifiers because it provides large values of current gain, voltage gain, and power gain.
5. Transistors magnify weak electrical signals applied to them.
6. A tiny input voltage in the transistor results in a huge output voltage.
7. A transistor works as an amplifier by taking in a very small weak signal through the base junction and raising the strength of the weak signal. This amplified signal is released through the collector.

A transistor acts as an amplifier by raising the strength of a weak signal.
