Energy Stored in Inductor Calculator
What is Energy Stored in an Inductor?
An inductor is a fundamental electrical component that stores energy in the form of a magnetic field when current flows through it. The energy stored in an inductor is an important concept in electromagnetism, circuit theory, and electrical engineering.
The energy stored in an inductor is given by the formula:
U = ½ × L × I²
Where U is the energy (Joules), L is inductance (Henry), and I is current (Ampere).
Understanding Energy Storage in Inductors
When electric current flows through an inductor, it creates a magnetic field. This magnetic field stores energy, which can be released when the current decreases. This property makes inductors essential for energy storage and transfer in circuits.
The energy stored depends on both inductance and the square of the current. This means even a small increase in current leads to a significant increase in stored energy. That is why inductors are crucial in high-current applications.
Inductors are widely used in power supplies, DC-DC converters, transformers, and filters. They help smooth current, reduce noise, and store energy temporarily for efficient circuit operation.
In switching circuits, inductors store energy when the switch is closed and release it when the switch is opened. This principle is used in boost converters and energy-efficient power systems.
How to Use the Calculator
- Enter any two values among Energy (U), Inductance (L), and Current (I).
- Leave one field empty.
- Click the Calculate button.
The calculator will automatically compute the missing value using the formula U = ½LI².
Example Calculation
If:
- L = 2 H
- I = 1 A
Then:
U = ½ × 2 × (1)² = 1 Joule
