A. 9.0H
B. 18.0H
C. 0.5H
D. 2.0H
Correct Answer:
Option A – 9.0H
Explanation
l =l1 + l2 = 3 + 6 = 9H
If two inductors of inductances 3H and 6H are arranged in series; the total inductance is?
![A coil of inductance 0.12 H and resistance 4Ω, is connected across a 240V, 50Hz supply. Calculate the current through it. [π = 3.142]](https://erudites.ng/wp-content/plugins/contextual-related-posts/default.png "A coil of inductance 0.12 H and resistance 4Ω, is connected across a 240V, 50Hz supply.
