See lessWhat is mutual inductance?
Mutual inductance is the phenomenon where a changing current in one coil induces a voltage in an adjacent coil, resulting in electromagnetic coupling between the two coils.

See lessExplain the operation of an inductor in an AC circuit.
In an AC circuit, an inductor resists changes in current flow by inducing a voltage that opposes the applied voltage, leading to phase shifts and energy storage in the magnetic field.

See lessExplain the concept of biasing in transistors.
Biasing in transistors involves applying a DC voltage or current to establish the operating point or quiescent point of the transistor, ensuring proper amplification and linear operation.

See lessWhat is the purpose of feedback in amplifiers?
Feedback in amplifiers is used to control gain, bandwidth, stability, and distortion, by feeding a portion of the output signal back to the input, either in-phase (positive feedback) or out-of-phase (negative feedback).

See lessDefine gain in amplifiers.
Gain in amplifiers refers to the ratio of output signal amplitude to input signal amplitude, indicating the amplification factor or the amount by which the signal is boosted.
