In Layman’s Terms
Inductance is a property of an electrical component (usually a coil or inductor) that opposes changes in the current flowing through it. It’s like a magnetic cushion that resists any sudden changes in current, helping to stabilize the flow of electricity.
In Technical Terms
Inductance, measured in henries (H), is the property of an electrical circuit that causes it to oppose a change in the current flowing through it, by inducing an electromotive force (EMF). The inductance (L) of a coil is determined by the number of turns in the coil, the area of the coil, and the material inside the coil (the core).

How It Works
When current flows through an inductor, it creates a magnetic field around it. If the current changes, the magnetic field changes, which induces a voltage in the opposite direction to the current flow. This induced voltage resists the change in current, creating inductance.
Key Components
- Coil: A wire wound into a series of loops that creates inductance.
- Magnetic Field: The area around the inductor where magnetic forces act.
- Henries (H): The unit of measurement for inductance.
Benefits
- Energy Storage: Inductors store energy in the form of a magnetic field.
- Filtering: Used in circuits to filter out unwanted frequencies.
- Stabilization: Helps stabilize current in power supplies.
Use Cases
- Transformers: Inductance is key in transferring energy between circuits.
- Filters: Inductors are used in tuning circuits to select specific frequencies.
- Energy Storage: Inductors store energy in switch-mode power supplies.
Security and Challenges
- Resistance to Current Change: Can cause delays in circuit response.
- Size: Inductors can be large, making them difficult to integrate into small devices.
In conclusion, inductance is a fundamental property that resists changes in current flow, playing a vital role in energy storage, filtering, and stabilization in electrical circuits.
