Answer to Question #144087 in Electric Circuits for sana

Question

Which statement about a transistor is true?
A) Acts as a half-wave rectifier
B) Has its own internal energy supply
C) Is used to rectify a.c. to d.c.
D) Functions as a current amplifier

Answer 1

The answer is option D. i.e transistor functions as a current amplifier.

For rectification or conversion of AC to DC generally diodes are used.

Transistor is a semiconductor sink it will never have an internal energy source. But when supplied it can be modelled as a dependent source.
