An inductor in an electrical circuit opposes the flow of current through it. An ideal inductor has no resistance or capacitance associated with its coil windings. A capacitor is another passive two-terminal electronic component that stores electrical energy in an electric field. The effect of a capacitor is known as capacitance.

A series RLC (Resistance Inductance Capacitance) small AC (Alternating Current) circuit consists of an AC source connected in series to a resistor (of resistance R), arranged in series with an inductor of inductance L, and in series with a capacitor of capacitance C.

This modeling and validation experiment consist of two parts. Each part is described as follows:

Part I: Analytically solving the governing equation of the circuit.

Part IIL Determining the circuit current using Multisim.
