# 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,

**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.**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.
