Where there is voltage,there must be current.Is this right
or wrong??
Answer Posted / punniyamurthy.g
wrong.
because for a current flow, the circuit should be closed
otherwise there is no current flow takes place
eg: battery.
when the voltage source is open then there is no flow of
current.
if we connect a load to a battery then current flow takes
place.

I have a drawing of a wound rotor induction motor for a crane. This crane motor has 5 forward speeds & 5 reverse speed implemented of course with different amount of resistance for each speed setting selected. What has got me scratching around is the fact that 8 of the 10 speed selections switch in uneven (unbalanced) amounts of resistances on each of the 3 connections to the motor's rotor.Can this be possible? I would have assumed this would produce unbalanced rotor currents and therefore vibration in the motor. I would greatly appreciate anyone's comments on this. Many thanks, Confused.
