Calculating the armature current of the motor.

[ramox3]

Homework Statement

A single-phase, full-wave controlled bridge rectifier supplies a permanent magnet dc motor. The rectifier is connected to a 240V ac voltage source and absorbs 1200W of active power and 1000VAR of reactive power from the source. If power loss in the rectifier is negligible, calculate the armature current of the motor.

Homework Equations

calculate the armature current of the motor.

The Attempt at a Solution

I don't know where to start.. any tips would be appreciated..

Active (or real) power can be thought of as a vector at right angles to reactive power.

Magnitude of power is voltage x current
