In a thermal power plant the prime mover is a steam
turbine. In order to obtain the rated speed in a turbine it
takes about 4 to 6 ours depending upon the type and
capacity of the turbine.

For these 2 devices what their power ratings are ? 1) single phase : AC 220V & starting amps 3Amps (i.e. starting torque) and the stabilized amps 2A ... For deep freezer 2) single phase : AC 220V & starting amps 2.7Amps (i.e. including the starting torque of a CRT monitor) and the stabilized amps 1 Amps thanks
