Question

In an amplifier, the output current flows for 200° of input cycle. The class of operation of the amplifier is
1. A
2. AB
3. B
4. C

Answer 1

Correct Answer - Option 2 : AB

In an amplifier, the output current flows for 200° of input cycle. The class of operation of the amplifier is Class AB because it is more than 180° and less than 360°.

For class A the angle of excursion is 360°

For class B the angle of excursion is 180°

For class AB the angle of excursion is >180° and < 360°

For class C the angle of excursion is less than 180°
