## What is a parallel RLC circuit?

Consider a RLC circuit in which resistor, inductor and capacitor are connected in parallel to each other. This parallel combination is supplied by voltage supply, VS. That is why parallel RLC circuit is said to have dual relationship with series RLC circuit.

How does RLC parallel circuit work?

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 the phasor diagram?

A phasor diagram is used to show the phase relationships between two or more sine waves having the same frequency. A phasor diagram is one in which the phasors, represented by open arrows, rotate counterclockwise, with an angular frequency of ω about the origin.

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 quality factor in parallel RLC circuit?

In a parallel RLC, It is defined as, resistance to the reactance of reactive element. The quality factor Q is also defined as the ratio of the resonant frequency to the bandwidth. Q = f r B W. For parallel RLC Circuit.

What happens in a RLC 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. RLC circuits have many applications as oscillator circuits. Radio receivers and television sets use them for tuning to select a narrow frequency range from ambient radio waves.

### Why impedance is maximum in parallel resonance?

As the total susceptance is zero at the resonant frequency, the admittance is at its minimum and is equal to the conductance, G. Since the current flowing through a parallel resonance circuit is the product of voltage divided by impedance, at resonance the impedance, Z is at its maximum value, ( =R ).

Why do we use phasor diagram?

The purpose of a phasor diagram is to provide an efficient graphical way of representing the steady-state inter-relationship between quantities that vary sinusoidally in time. We picture all phasors to be rotating anticlockwise at a constant speed and completing one revolution per cycle of the supply.

## What is the phasor diagram of a RLC circuit?

Phasor Diagram of Series RLC Circuit. For Series RLC circuit, depending upon the value of XL and Xc voltage can either lead or lag the current. if XL is greater than Xc then the voltage will lead the current. if Xc is greater than XL then current will lead the voltage. This leading angle φ = tan-1(XL-Xc/R)

Which is parallel circuit in the RLC series?

RLC Parallel circuit is the circuit in which all the components are connected in parallel across the alternating current source. In contrast to the RLC series circuit, the voltage drop across each component is common and that’s why it is treated as a reference for phasor diagrams. In…

### How are resistor and inductors represented in RLC series circuit?

Voltage across each component in RLC series circuit : The voltage drop in resistor will be in phase with current, in case of the capacitor the current will leads voltage drop and for the inductor, the current of the inductor will be lag from voltage drop in the inductor. The same thing is represented with the phasor diagram.

What do you need to know about RLC circuit calculator?

RLC circuit calculator calculates the inductive impedance, capacitive impedance, total impedance, and total current. It also calculates the voltage across resistor, inductor, and capacitor and the phase angle between the current and voltage.
