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))
- Formula: U = I²·L/2
- Substitute the values: U = 5·7²/2
- Result: U = 122.5 J
Answer: U = 122.5 J
