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.

0.5 H
1.25 H
0.25 H
0.75 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

A 200/400 V, 20 kVA, 2-winding transformer is connected as an auto-transformer to transform 600 V to 200 V. Calculate the kVA rating of the auto-transformer.

50 kVA
25 kVA
60 kVA
30 kVA

ANSWER EXPLANATION DOWNLOAD EXAMIANS APP

Here auto transformer change voltage from 600 V to 200 V.
Voltage ratio (a) = 600/200 = 3
kVA rating of the auto-transformer = (a/(a - 1))*(kVA rating of auto transformer)
= (3/2)*20
= 30 kVA
