What are the applications of RLC circuits?  

In addition to electronic applications, there are many other applications for power transmission.  

In order to maintain good voltage distribution in medium to long-distance transmission, capacitor and inductor compensation technologies are used.  

It can also be used for neutral grounding of generators/power transformers to avoid sudden fault currents.  

In CFL bulbs, the RLC circuit is used to increase the working power factor of the lamp to reduce electricity consumption.  

In industry, most motors are induction type, which may cause significant voltage drops at the power supply point to avoid the problem of capacitor banks being equipped in every industry.  

The combination of a notch filter and a CVT is used as a low-pass filter to prevent communication signals from entering the power transformer. The notch filter here is used as an inductor, and the CVT is used as a capacitor.  

In terms of electricity (AC), every device that operates using a magnetic field is an RL circuit. The operation of these devices results in a decrease in terminal voltage due to magnetic effects. To compensate for the voltage drop, a capacitor was used at its terminal. So this is an RLC circuit.
