Q:

How is the flux of shunt coil related to voltage?

A) flux is proportional to square of voltage B) directly proportional
C) inversely proportional D) independent of each other
 
Answer & Explanation Answer: A) flux is proportional to square of voltage

Explanation: In an energy meter, the supply voltage may fluctuate as a result of unavoidable reasons leading to errors in the reading. Supply voltage causes the shunt flux to induce an e.m.f in the disc. This is results in a self braking torque proportional to square of the voltage.
