How do you draw a phasor diagram of a LCR circuit?
- As shown in the phasor diagram, the voltage across the inductor L is leading the current with a phase 2π
- and the voltage across the capacitor is lagging the current by a phase 2π.
- the voltage across the resistor is in phase with the current so the vector representing VR is parallel to that for I.
What are phasors give its graphical representation?
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 a phasor diagram illustrate it with an example?
Answer. 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 will be the length of the phasor in LCR circuit?
The length of the phasors represents the peak values (Im XL, ImXC and ImR) . From the circuit , VR + VC + VL = V. Refer figure(2) from the phasors a right triangle is obtained whose hypotenuse =V . Comparing the above equation with V=IR , then R = √( R2 + (XC – XL)2).
What are phasors and 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.

What do you mean by Phasors?
Definition of phasor : a vector (as one representing an alternating current or voltage) whose vectorial angle represents a phase or phase difference.
Why are phasors useful?
Though we won’t dwell on it here, one of the important reasons we use phasors is because it turns the problem of differentiation and integration to an algebraic problem. If we have function f(t), the phasor representation is F, and the rotating vector is Fejωt.
