Two-wattmeter method is used to measure the power taken by a 3-phase induction motor on no load. The wattmeter readings are 400 W and -50 W. Calculate the reactive power taken by the load

450√3 VAR
450/√3 VAR
350√3 VAR
350/√3 VAR

ANSWER EXPLANATION DOWNLOAD EXAMIANS APP

Reactive power taken (Q) = √3*(W1 - W2)
= √3*(450 + 50)
= √3*450 kVAR

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
0.25 H
0.5 H
1.25 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

4.5 V
3.5 V
1.5 V
2.5 V

ANSWER EXPLANATION DOWNLOAD EXAMIANS APP

Equation is given by:
Vds = Vgs - Vt
Vds = 3 - 0.5
Vds = 2.5 V
