Compute the induced emf, Electrical Engineering

Assignment Help:

Compute the induced emf:

If a coil of 150 turns is linked with a flux of 0.01 wb while carrying a current of 10 Amp, compute the inductance of coil. Now, if current is reversed uniformly in 0.1 sec, compute the induced emf.

Solution

The self inductance of coil is

L = N φ / I = (150 × 0.01)/10= 0.15 Henry

The induced emf e = - L (di /dt)

=-( L (i2 - i1) )/dt

=- L [- 10 - 10] / 0.1

 = 30 volt.
