Let T be the net torque developed by the rotor runs at ω rad/s. What is the mechanical power developed?

If an alternator is operating at unity power factor, then its terminal voltage is

In the circuit shown, find the equivalent resistance between A and B.

The below symbol which is used in single line diagrams represents

P = ρQHg is the water power equation. Head ‘H’ is measured in meter ‘g’ gravity constant is measured in meter/second square, then the measuring unit of ‘Q’, the flow rate of water is:
