# What is the RLC series circuit?

## What is the RLC series circuit?

An RLC circuit is an electrical circuit consisting of a resistor (R), an inductor (L), and a capacitor (C), connected in series or in parallel. The name of the circuit is derived from the letters that are used to denote the constituent components of this circuit, where the sequence of the components may vary from RLC.

### What is the formula of RLC series circuit?

For a series RLC circuit, and impedance triangle can be drawn by dividing each side of the voltage triangle by its current, I. The voltage drop across the resistive element is equal to I*R, the voltage across the two reactive elements is I*X = I*XL – I*XC while the source voltage is equal to I*Z.

#### What is series and parallel RLC circuit?

In series RLC circuit, the current flowing through all the three components i.e the resistor, inductor and capacitor remains the same, but in parallel circuit, the voltage across each element remains the same and the current gets divided in each component depending upon the impedance of each component.

What is condition of series RLC resonance circuit?

In RLC series circuit, when the circuit current is in phase with the voltage, the circuit is said to be in Series Resonance. The resonance condition in the circuit arises when the inductive reactance is equal to the capacitive reactance.

What is a parallel RLC circuit?

In parallel RLC Circuit the resistor, inductor and capacitor are connected in parallel across a voltage supply. The parallel RLC circuit is exactly opposite to the series RLC circuit. The applied voltage remains the same across all components and the supply current gets divided.

## What is XC and XL?

In series RLC circuit, the condition XL(Inductive reactance) = XC (Capacitive reactance) is called resonance condition. In this condition the inductive reactance get cancelled by capacitive reactance. So,the entire RLC series circuit just acts as a resistive circuit. So,the power factor is unity.

### What is impedance in RLC circuit?

Impedance is the term that describes the characteristics of an electronic component in resisting current flow. It sounds similar to resistance, but impedance is proportional to frequency change. An RLC circuit consists of a resistor, inductor, and capacitor.
