R/sir First of all thank you very much for your technical videoes. I want to know regarding the contactor coils. How to determine that the coils are weak or not. There are several types of contactor with coil resistance. How to calculate there minimum and maximum coil resistance and when it will change to prevent breakdown. Thank you very much sir Regards
