Assessment: JAMB UTME - Physics - 2004 Subject: Physics

Question 1 Report

9.0 x 10-3J

9.0 x 10-2J

1.4 x 10-2J

1.8 x 10-3J

Answer Details

The energy stored in an inductor can be calculated using the formula: E = 0.5 * L * I^2 where E is the energy stored, L is the inductance, and I is the current flowing through the inductor. Substituting the given values, we get: E = 0.5 * 5mH * (6A)^2 First, we need to convert millihenry (mH) to henry (H): 1mH = 0.001H Therefore, E = 0.5 * 0.005H * (6A)^2 Simplifying, E = 0.09J So the energy stored in the inductor is 0.09J. Therefore, the correct option is: 9.0 x 10-2J.
