## What is phasor diagram of RL Series circuit?

Phasor Diagram of the RL Series Circuit The voltage drop across the inductive reactance VL =IXL is drawn ahead of the current I. As the current lags voltage by an angle of 90 degrees in the pure Inductive circuit. The vector sum of the two voltages drops VR and VL is equal to the applied voltage V.

**What is the expression of RL Series circuit?**

In case of series RL circuit, resistor and inductor are connected in series, so current flowing in both the elements are same i.e IR = IL = I.

**What is the impedance of RL Series circuit?**

Series RL Circuits Therefore, the two voltage drops (VR and VL ) are out of phase, based on the current I. When a sine wave is applied to an RL series circuit, the initial opposition to current flow is a series combination of R and X1. This total opposition (combination) is known as impedance, symbolized by Z.

### What is phasor and phasor Diagram?

Phasor Diagrams are a graphical way of representing the magnitude and directional relationship between two or more alternating quantities. Sinusoidal waveforms of the same frequency can have a Phase Difference between themselves which represents the angular difference of the two sinusoidal waveforms.

**What is the formula for RL?**

These equations show that a series RL circuit has a time constant, usually denoted τ = L/R being the time it takes the voltage across the component to either fall (across the inductor) or rise (across the resistor) to within 1/e of its final value.

**What is power factor of RL Series circuit?**

The power factor of an R – L circuit is 1/√(2) .

## How does an RL circuit work?

A LR Series Circuit consists basically of an inductor of inductance, L connected in series with a resistor of resistance, R. The resistance “R” is the DC resistive value of the wire turns or loops that goes into making up the inductors coil.

**What is the phasor diagram illustrate it with an example?**

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 phasor diagram in AC circuit?**

Phasor diagrams are the representations of voltage-current relationship in AC circuits. A phasor is a vector capable of rotating about the origin with (angular velocity) ‘ω’. The vertical component of phasor will represent the sinusoidally varying quantity.

### 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 phasor and phasor diagram?**

**What is phasor diagram of AC circuit?**

Phasor Diagram A phasor is a scaled line whose length represents an AC quantity that has both magnitude (peak amplitude) and direction (phase) which is frozen at some point in time. A phasor diagram is used to show the phase relationships between two or more sine waves having the same frequency.

## How do you draw a phasor diagram for an RLC circuit?

Step – I. In case of series RLC circuit; resistor, capacitor and inductor are connected in series; so, the current flowing in all the elements are same i.e I r = Il = Ic = I. For drawing the phasor diagram, take current phasor as reference and draw it on horizontal axis as shown in diagram.

**What is phasor diagram of alternating current?**

A phasor diagram represents the phase relationship between the alternating current and alternating e.m.f. The peak values are represented by the arrows called phasors which can be rotated in the anticlockwise direction.

**How does a phasor diagram work?**

A Phasor Diagram can be used to represent two or more stationary sinusoidal quantities at any instant in time. Generally the reference phasor is drawn along the horizontal axis and at that instant in time the other phasors are drawn. All phasors are drawn referenced to the horizontal zero axis.
