Applications and Examples of RL, RC, LC, RLC Circuits

Here in this article, we are going to know the uses, applications, and practical real-life examples of RL, RC, LC, and RLC Circuits. Before going to examples first of all we must know about these circuits. The 'RL' where R indicates the resistance and the L indicates the Inductance, so the RL circuit has both resistive and inductive elements either connected in series or in parallel. The 'RC' where R indicates the resistance and C indicates the Capacitance, so the RC circuit has both Resistive and Capacitive elements either connected in series or parallel. Similarly, 'LC' where L indicates the Inductance and C indicates the Capacitance, so the LC circuit has both Inductive and Capacitive elements either connected in series or parallel. The RLC circuit has all the resistive, inductive, and capacitive elements.

RL Circuit Examples

The practical examples of RL Circuits are,

1. Ceiling Fan with Resistive Regulator Circuit - Yes, we know that the ceiling fan is built with an electric motor that is an inductive load or inductive element and the old resistive fan regulator is a resistive element. It can be called as a series RL circuit because the fan regulator is connected in series with the inductive coil of the fan.
2. Capacitance Compensator Circuit - An inductor is connected in parallel with the load resistor of any amplifier or processing circuit to compensate for the capacitance loading effect.
