Stored Energy vs Inductance
Formel
## Energy in an Inductor An inductor stores energy in its magnetic field when current flows through it. ### Formula **E = (1/2) * L * I²** This energy is released when the current decreases. The magnetic field collapses, driving current through the circuit.
Lösungsbeispiel
A 100 mH inductor carrying 2 A.
- 01E = 0.5 * L * I²
- 02E = 0.5 * 100e-3 * 4
- 03E = 0.5 * 0.4
- 04E = 0.2 J = 200 mJ
Häufig Gestellte Fragen
Where is inductor energy storage used?
Inductors store energy in switch-mode power supplies, DC-DC converters, and energy harvesting circuits where energy is rapidly cycled.
What happens to the energy when current is interrupted?
The collapsing magnetic field generates a voltage spike to try to maintain current flow. This is the principle behind ignition coils and boost converters.
How does inductor energy compare to capacitor energy?
Capacitors store energy in an electric field (E=0.5CV²), inductors in a magnetic field (E=0.5LI²). Both are proportional to the square of the respective variable.
