Energy in inductor

U = ½LI²

Where: I = moment of inertia (kg·m²) / current (A), L = length (m) / angular momentum / inductance, U = potential energy (J)

Solved example

Given: I = 7, L = 5
Find: U (potential energy (J))

  1. Formula: U = I²·L/2
  2. Substitute the values: U = 5·7²/2
  3. Result: U = 122.5 J

Answer: U = 122.5 J
