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 right answer is option *C*
120/90 = 4/3.
4/3+1.3 = 2.63.
120/90 = 4/3.
4/3+1.3 = 2.63.

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.
