Esa too much direct formula nai h bhai. Copper wire ke quality pe Resistivity ka value pe v depend karta h resistance. Waise aapki dp achi h. Dr. Kalam 🙏🏼
Good question sir. Material kaisa use Kiya h us pe depend karega Resistance. Jis motor ka cost jyada hai, uska resistance Kam hoga kyun k wo ache quality of copper bana hoga. Uske wire Area (diameter) jyada hoga, matlab mota jyada hoga.
5% se jyada nai hona chahiye as per my experience nai too current same nai hoga 3 windings me ar motor trip karega on current imbalance or ground fault
I mentioned in video , the values can change as per motor make, different companies use different materials for winding, some can be of good quality hence less resistance and vice versa. Even I get different readings for same rating motor of different make,all can't be same. Only formula I can say is as power rating increase its resistance decrease.

बड़े मोटर में रेजिस्टेंस कम क्यू होता हैं और छोटे मे ज्यादा ?
क्योंकि छोटी मोटर वाइंडिंग का क्रॉस-सेक्शनल क्षेत्र बहुत कम होता है क्योंकि उनमें करंट कम होता है
resistance different kyo h same ratting me..... eska reason?

Jis motor ka cost jyada hai, uska resistance Kam hoga kyun k wo ache quality of copper bana hoga.

What's GRR ?
@@bishantkumar12589 sir for as examples 4509 kW slipring motor have 2035 Rotor voltage & 1136 rotor current how to calculate ( Grid rotor Resistance ) vale ????
For HT motor micro ohm need
Yes true. Resistance values are too low, in mirco ohms
What if resistance is zero(30kw motor) but motor is running how possible
Resistance will never be Zero. Practically not possible bro.
