How much current is flowing throught the motor

Reference no: EM13492490

A circular armature coil is used in a motor with a uniform magnetic field of 1.80 T. The coil has a diameter 95 cm, a resistance of 25 Ω, and generates a back emf of 94 Vrms when running a full speed under no load at the angular frequency ωA. If this motor is operating on 120 Vrms with a no-load angular frequency ωA, how much current is flowing throught the motor?
