Question

For a transistor amplifier, the voltage gain (a) remains constant for all frequencies. (b) is high at high and low frequencies and constant in the middle frequency range. (c) is low at high and low frequencies and constant at mid frequencies. (d) None of the above.

Answer 1

A transistor amplifier is a current control device. If the current is controlled then, it can be used to find voltage gain.

The voltage gain of a transistor amplifier is constant in the middle frequency range and at the high frequencies and the low frequencies, the voltage gain will be low.

Hence, the correct statement is (c).
