why the starting current of a motor is high?

Answer Posted / sanjana singh

in starting motor resistance is negligible.so according to formula-
I=v/Ra ( Ra can be neglected)
then I=V ( Starting current is equal to supply voltage)
so to start motor starter is used. it add resistance in series of motor by this starting current limit to safe value & motor start safely...
