Step 1
3.1 Explain the term inductance with reference to RLC circuits connected to an AC supply.
Answer
Inductance is a property of an electrical circuit that produces a back electromotive force (back-emf) when the current changes. In RLC circuits, this property is crucial because it determines how the circuit reacts to alternating current (AC). When an AC supply is connected, the changing current generates a magnetic field around the inductor, which in turn creates a voltage that opposes the change in current. This behavior is fundamental in applications like filters and oscillators.
