Question

What is transistor gain?

Answer 1

Transistor:

1. A transistor is a kind of miniature semiconductor device that can regulate or control current or voltage flow in any direction.
2. It can also amplify and can generate these electrical signals and act as a switch/gate for them.
3. Basically, a transistor consists of three layers, or say terminals, of some semiconductor material, each of which can carry some quantity of current.

Transistor gain:

1. When we undertake some calculations, while we design an electronic circuit, the transistor current gain often terms in the Greek letter Beta $\left(\beta \right)$
2. This is known as forwarding current gain for the transistor while operating in a common emitter type of mode.
3. The factor $\alpha /1-\alpha$ is called $\beta$ Beta, which is known as the common emitter current gain.
4. The current gain for the common-base configuration may be defined as the change in collector current divided by the change in emitter current when we keep the base-to-collector voltage constant.

The common emitter current gain is transistor gain.
