In this video, phasor, and Phasor Diagram for AC circuits have been explained. And at the end, voltage and current relationship between the basic circuit elements like resistor, inductor, and capacitor has been explained using phasor diagram.
What is Phasor?
Phasor is one of the ways by which we can represent AC sinusoidal signals and we can perform arithmetic operations onto these sinusoidal signals.
Phasor is rotating the vector, which rotates around its origin at angular speed w rad/sec in anti-clockwise direction. The length of this vector represents the maximum amplitude of the sinusoidal signal and the angular velocity represents the angular frequency of the sinusoidal signal.
When phasors are represented on phasor diagram they are represented by only amplitude and phase of sinusoidal signals.
(Frequency is not represented because phasor diagram is used for signals which have same frequency but different phase and amplitude)
What is phasor diagram?
As its name suggests, phasor diagram is used to represent the phase difference between the sinusoidal signals which have the same frequency but different phase and amplitude.
Using this phasor diagram, it is easy to analyze different sinusoidal signal signals which have the same frequency.
Mathematically these phasors can be represented in three different forms.
1) Polar Form
2) Rectangular Form
3) Exponential Form
In this video, it has been shown that how to represent phasor in this three forms.
And at the end, voltage and current relationship between the basic circuit elements like resistor, inductor, and capacitor has been explained using phasor diagram.
1) Resistor: For resistor, Voltage and current will be in phase
2) Inductor: For inductor, voltage will lead the current by 90 degree
3) Capacitor: For capacitor, current will lead the voltage by 90 degree
Timestamps for the different topics in the video is given below:

sir yr video on phaser and phaser diagrams in ac circuit:_ I have no words to express my gratitude for yr above brilliant VEDIO. During my COLLEGE/technical institution days i had tried my BEST to understand these things but in vain. None of the books nor my teachers lecture HELPED ME TO grasp their significance. Even till today i REMEMBERED all the equations and differenciations but blindly. But now today After yr brilliant tutorial i could appreciate their significance. I understood every small bit u explained there. the video Is a classic EXAMPLE OF how a number of information can be in one small video that too completely clearing all doubts without intimidation. thank u s.vatsa, Bangalore.

when we draw the phasors in the plane, which value should be taken ? maximum or RMS ? is there any hard and fast rule that we always need to take only the RMS value of an AC quantity for phasor diagrams ?

@ALLABOUTELECTRONICS 6 жыл бұрын

Well, there is not hard and fast rule. Some textbook takes RMS value while some textbook takes the maximum value. Some textbooks take RMS value because most of the AC signals are represented in RMS value. (e.g 230 V, 50 Hz AC Signal). But, there is no hard and fast rule.

@ALLABOUTELECTRONICS 5 жыл бұрын

It is in polar form. Im< phi. and 90 degree is phase shift is introduced due to differentiation. e^(j pi/2) can be written as cos(pi/2)+ j sin (pi/2). cos(pi/2) = 0 and sin (pi/2) =1 That's why e^(jpi/2) = j.

If your real axis is horizontal and your imaginary is vertical then you need to replace all of your sines with cosines. When the angle is zero all of the magnitude is on the real axis, but your sin is zero. Common mistake though.
