A two-phase generator is connected to two 90 
load resistors. Each coil generates 120 V ac. A common neutral line exists. How much current flows through the common neutral line?

The 2 resistors are connected in parallel or series, the result (I) may vary accordingly.

The circuit will be balanced due to the same amount of load on both phases and so the current through the neutral wire must be zero.

The guys saying that for balance load no current follows through the neutral should think that neutral is common here. So answer 2.66.

Please explaination of this answer.

This is wrong the answer is c. The neutral will have sum of both the line currents.

Wrong answer...correct answer is (1.88) I in neutral= (120/90)+((120/90)<90)=1.88 magnitude
