Answer / shailendra

we can use 200w bulb insted of choke. or
we can use about to one bucket water. in
the place of choke connect two electrode
of battery cell and drop both electrode
in water bucket.

Answer / katrina kaif

becuse current passes through to choke\coil if we are not using choke so we do the short of rode wire.

if the 10 hp motor name plate indicates rated current as 13.6 amp the what will be the thermal relay setting? Why? And in how much time relay will trip at the set value?
