The energy stored in an inductor of inductance ... - JAMB Physics 2004 Question
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 option: b
Energy stored in a coil of inductance, L, and carry a current, I is given by
E = 1/2 L I2
= 1/2 x 5 x 10-3 x 6 x 6
= 9.0 x 10-2J
E = 1/2 L I2
= 1/2 x 5 x 10-3 x 6 x 6
= 9.0 x 10-2J
