Stored Energy vs Inductance
公式
## Inductor Energy Storage **E = 0.5 x L x I^2** Energy is stored in the magnetic field. It scales with the square of current.
计算示例
10 mH inductor carrying 1 A.
- 01L = 10 mH = 0.01 H
- 02E = 0.5 x 0.01 x 1^2 = 0.005 J = 5 mJ
常见问题
Where is the energy stored?
In the magnetic field surrounding the inductor coil.
What happens when current is interrupted?
The inductor generates a voltage spike (back-EMF) trying to maintain current flow. This can damage circuits without protection.
Inductor vs capacitor energy?
Capacitor: E=0.5CV^2 (electric field). Inductor: E=0.5LI^2 (magnetic field).
