A rectangular conductor is 1.6 inches wide and 0.25 inch thick. What is its area in square mils?

40000 square mils
400000 square mils
400 square mils
4000 square mils

ANSWER EXPLANATION DOWNLOAD EXAMIANS APP

1.6 inches = 1.6 inches x 1,000 mils per inch = 1,600 mils
0.25 inch = 0.25 inch x 1,000 mils per inch = 250 mils
Area = 1,600 x 250 = 400,000 square mils

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
0.5 H
1.25 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
