1. What are the main uses of inductors?
Used for filtering, smoothing power output.
Provide impedance in AC circuits.
Energy storage and release.
As part of a transformer.
Used in oscillating circuits. -
2. What are inductors in simple terms?
An inductor is a component that can store magnetic energy and resist changes in current.
-
3. Why do inductors block AC?
Inductors present low impedance to DC, but for AC, due to the back electromotive force generated inside them, the impedance provided by the inductor increases as the frequency increases, so it can be considered to "block" high-frequency AC components.

4. How is the current through an inductor in an RLC circuit calculated?
To calculate the current in an inductor in an RLC circuit, the AC version of Ohm’s law can be used, where the current (I) is equal to the voltage across the inductor (V_L) divided by the inductive reactance (X_L), calculated as follows X_L = 2πfL (where f is the frequency and L is the inductance of the inductor) – Formula: I = V_L / (2πfL); In a series RLC circuit, the current through the inductor will be the same as the current flowing through the entire circuit due to the series connection.
