An RLC circuit is an electrical circuit that consists of three main components: a resistor (R), an inductor (L), and a capacitor (C). These components work together to control the flow of electric current. The resistor limits the current, the inductor stores energy in a magnetic field, and the capacitor stores energy in an electric field. RLC circuits can be found in various applications, including radios and filters. RLC circuits can be classified as either series or parallel circuits, depending on how the components are connected. In a series RLC circuit, the components are connected one after another, while in a parallel RLC circuit, they are connected across the same voltage source. The behavior of these circuits can be analyzed using Ohm's Law and Kirchhoff's Laws, which help in understanding how voltage and current behave in the circuit.
