| Difference between induction motor and synchronous motor?
i Think Synchronous motors operate at synchronous speed
(RPM=120f/p) while induction motors operate at less than
synchronous speed (RPM=120f/p – slip). Slip is nearly zero
at zero load torque and increases as load torque increases
am a right pls guide & send Other Comments |

| Can u explain : how capacitor act when the supply is given
is a.c and d.c.
I know that when d.c supply is given then the capacitor
charges and becomes open circuited.
But please say about when a.c is given.
I have seen that when a.c supply is given ,it charges and
discharges,
But when we plug in capacitor to our daily supply and take
it out ,then we join those wires spark will appear,which
seems charge is present ,but when a.c is given it should
charge and discharge |
