The current in the coil of a large electromagnet falls from 6 A to 2 A in 10 ms. The induced emf across the coil is 100 V. Find the self-inductance of the coil.

0.75 H
1.25 H
0.5 H
0.25 H

ANSWER EXPLANATION DOWNLOAD EXAMIANS APP

Equation of self inductance:
V = Ls*(di/dt)
Ls = V/(di/dt)
= 100/((6 - 2)/(0.01))
= 0.250 H
= 250 mH

The sending end and receiving end voltages of the short transmission line are 150 kV and 120 kV respectively. Calculate its percentage voltage regulation.

30%
20%
25%
40%

ANSWER EXPLANATION DOWNLOAD EXAMIANS APP

Where,
Vs - sending end voltage in kV
Vr - Receiving end voltage in kV.

Voltage regulation = (Vs - Vr)/Vr
= (150 - 120)/120
= 0.25
% R = 25 %
