Answer Posted / rajesh tokalapudi
In case of motor current is given by i=(v-e)/r.here
v=suplly voltage,e=back emf and r=resistace.during starting
back emf is zero.then i=v/r.generally motor resistance is
low.so during starting motor draws high current,which is
normally 5 to 6 times its normal operating current.
