Question

If the flux associated with a coil changes at the rate of 360 webers every 4 minutes, then the induced e.m.f. is ______

Options

• 2 volt

• 0.20 volt

• 1.5 volt

• 6 volt

Answer 1

If the flux associated with a coil changes at the rate of 360 webers every 4 minutes, then the induced e.m.f. is 1.5 volt.

Explanation:

|e| = `(dphi)/dt = 440/(4 xx 60)` = 1.5 V
