15:11 , you said that to we need that the value of Xl be equal to Xc so that they cancel each other out. But the circuit is in parallel to each other. So I guess that what you mean by cancel each other out is when we get their respective reactive power is that the plot of Q of L and Q of C will cancel each other? Am I right?
One thing I don't really get; in the video the circuit has a true power of 720 W and a reactive power of 720 VAR. When I look at the graphical display (@ 7:05) I only see a small portion of the power sine wave going negative. Can you explain/show me why the VAR amount is that large in numbers, but that small on the graphical display? Thank you in advance
1.sir can u pls explain why there is some phase difference when it comes to inductor & capacitor wheather it has any physical significance or not?? 2.sir what is load angle how it will come in synchronus generator??
Does applying Power Factor Correction (PFC) to the home appliances (say, only there are linear loads) will reduce our bill (KWh)? Will it benefit home users if PFC is applied?
4:52 its source to load not load to source it seems. you should have apply VICoso& VIsino formulas to calculate Real & Reactive power.its good video nice keep it up.
Reactive power is nothing but the power oscillations in the circuit due to inductors and capacitors present. It is really confusing when we are studying reactive power only with the phasor diagram, I have explained the concept with the help of fundamental waveforms in my Chanel. Also explained why reactive power compensation is necessary, how we can compensate.
very fast explained in basic section... value of XL taken directly ?? capacitor connection in improvement should series / parallel explain ? what about RLC / RC circuit ?
Timestamps for the different topics in the video is given below: 0:43 What is Power Factor? 2:40 Power in Purely Resistive load 4:06 Power in Purely Reactive load 6:15 Power in practical load (Resistive + Reactive) load 10:28 Lagging and Leading Power factor 11:30 Significance of Power Factor 12:55 Power Factor Correction 17:58 Displacement and Distortion Power Factor
calculating power factor in a house using impedance and resistance is tiresome. If you know the phase angle between voltage and current , you can find p.f. easily by taking the cosine of that angle. That angle will be found out by the electricity meter installed at home
I now understand how he gets 80 ohms, it's because 3 amps will flow through the capacitor. What I don't get yet is the value of the total impedance to equal 80 ohms
well here what I meant to say was, Inductive and capacitive reactive power should be equal. So, that no additional power will be drawn from the source. So, for unity power factor QL= QC.
Hi sir.. The video was nice... But my doubt is how to find the component is purely resistive or reactive by impedence triangle diagram... From clip 16:49
Here, the voltage source is 240 V, 50Hz. So, the value of XL ,which is j40 is for 50Hz. And here we are assuming that the voltage source frequency is not changing. So, that is why frequency is not included for the calculation of I. I hope it will clear your doubt.
normally we do not use a capacitor in serial. capacitors connect parallel to the circuit. if we connect serial capacitor whole circuit working differently.
Reactive power kahi pe dissipate nahi hota. Woh magnetic filed generate karne mein use hota hai. Like, fan mein motor ke andar magnetic filed generate hoga tabhi woh rotate ho sakta hai. So, ye magnetic filed reactive power se generate hota hai. Koi bhi load mein jo resistive part hai ussi mein power dissipate hota hai.
