The type of amplifier coupling that uses inductive action is ________.
A) direct
B) capacitive
C) transformer
D) transistor

Question

Quizplus · Accepted Answer

Transformer coupling uses inductive action to transfer the signal from the primary winding to the secondary winding. This coupling method is commonly used in audio amplifiers as it provides galvanic isolation and high voltage gain. Direct coupling does not use any coupling component and capacitive coupling uses a capacitor to transfer the signal. Transistor coupling refers to different biasing methods used in transistor amplifiers. Therefore, the best choice for a coupling method that uses inductive action is transformer coupling.
