The energy stored in an inductor of inductance 5mH when a current of 6A flows through it is
-
A.
9.0 x 10-3J
-
B.
9.0 x 10-2J
-
C.
1.4 x 10-2J
-
D.
1.8 x 10-3J
Correct Answer: Option B
Explanation
Energy stored in a coil of inductance, L, and carry a current, I is given by
E =
1/
2 L I
2
=
1/
2 x 5 x 10
-3 x 6 x 6
= 9.0 x 10
-2J
