A split-phase motor has the following parameters : main winding effective resistance is 4ohm and effective reactance is 8?, and auxiliary winding effective resistance is 8ohm and effective reactance is 4ohm. If the line voltage E is 120V, calculate (a) The magnitude of Ia and Is; (b) The phase angle between Ia and Is; (c) The line current IL. Addtional info: Auxillary winding= 70 turns/pole and #22 wire, Main windings = 120 turns/pole and #16 wire.
13A flows through the coil of a DC motor. The coil has a length of 0.4m and 0.3m. The coil has 36 windings and a flux of 0.21 Wb. If its rotational frequency is 936 r/min, calculate output power of the motor.
An electronics manufacturer makes corrosion-resisitant, gold-plated connectors. Each connector is cylindrical in shape with a diameter of .100 cm and a length of 1.0 cm. Each connector is to be coated with a 10 -(micrometer) gold layer.
