The current gain of a PNP transistor is

Electrical Engineering XYZ MCQs

The current gain of a PNP transistor is:

1. Near zero
2. The negative of the npn current gain
3. The ratio of collector current to emitter current
4. The collector current divided by the emitter current

Correct answer: 3. The ratio of collector current to emitter current

Explanation: The current gain of a transistor is a measure of how much the transistor amplifies current. In the case of a PNP transistor, the current gain is defined as the ratio of collector current (Ic) to emitter current (Ie), often denoted as β (beta).
