Question

Does a transistor amplify voltage?

Answer 1

Explanation:

A transistor can amplify current, or voltage, or both, depending on how it is configured in the circuit.

1. If it is configured as a common collector then it amplifies current, but not voltage.
2. If it is configured as a common base then it amplifies voltage, but not current.
3. If it is configured as a common emitter then it amplifies both current and voltage.

Hence, a transistor amplifies voltage if it is configured as a common base and common emitter.
