A single phase wattmeter is used to determine the power taken by a three phase squirrel cage induction motor. The current coils is placed in line 1 while the potential coil is shifted from lines 1 and 2, then from lines 1 and 3 respectively. If the wattmeter registers 5760 and 3380 watts respectively, what is the line current drawn by the motor. Line to line voltage is 230 V.
