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

In a balanced 3 phase circuit effective neutral is alwayas zero.

In balanced circuit there will ne no neutral current. (I=0A).

Here 3ph generator connected to a 3ph Resistive load. A common neutral line exist implies both generator and the resistive load neutral is grounded. ONCE neutral is grounded, current through neutral is zero. 3In= Ia+Ib+Ic....

In a balanced 3 phase circuit neutral current is always zero.

Absolutely Right, Because in three phase system neutral current will be zero if three phases are balanced condition.

In three phase balance circuit, The neutral current is zero.

Because suppose condition is not balanced than what happening?

Each coil generates 120V AC means that operation is balanced and neutral implies that there is star connection and we have no current flow through neutral.

Neutral is always zero potential difference.

Surely the neutral current in balanced 3 phase circuit equal to zero.
