Hi Varun, you mentioned that the capacitor starting motor gives you more torque than resisive starting so I had to think about that of course. I think it's for two reasons, first with Xc > Xa the reactance Xa - Xc goes capacitive as you have shown, Well that of course kicks the angle between Ia and Im more that it could with an added restistor to the auxillary winding. That is theta = (theta m- theta a) for resistibe is still in inductive quadrant, and theta = (theta m - (- theta a)) is kicked into capacitve quadrant, therefore theta for... Ia sin theta is naturally closer to 90 and therefor closer to one. Then on top of that Xc actually lowers auxillary impedance as it offsets Xa and therefore ia ampliture is higher than if we add a resistor to aux winding. so both affects make torque induced in the rotor greator for the added cap over added resistance to aux winding. Just thinking outloud Sir ! Hope you are well !
Namaskar, sir. Will you please tell me, how can I make a comparison of the starting torque of a permanent split-capacitor motor to that of a capacitor-start motor of the same size?
Loved the bloopers 😂😂

Plss explain the concept of crawling
Sir how the capacitor run induction motor improves power factor
when will you post the numericals solving video
There are many numerical spread out the course...
Electrical Is Easy Yes i know but i’m asking only for the single phase IM
