What is an Inductor?
An inductor is a passive electronic component that stores energy in the form of a magnetic field when current flows through it. It resists changes in current flow, similar to how a capacitor resists changes in voltage.
How Do Inductors Work?
When current flows through an inductor, a magnetic field is created around it. This magnetic field stores energy, which is released when the current changes. Inductors effectively smooth out changes in current, acting as a buffer against sudden spikes or drops.
Types of Inductors
There are various types of inductors, including:
- Fixed Inductors
- Variable Inductors
- Mutual Inductors
- Toroidal Inductors
Applications of Inductors
Inductors are used in a wide range of electronic circuits, including:
- Power Supplies
- Filters
- Tuners
- Transformers
Case Study: Inductors in Power Supplies
In a power supply circuit, inductors are used to filter out AC noise and ripple from the DC output. This ensures a stable and clean power supply for sensitive electronic devices.
Statistics
According to a recent survey, the global inductor market is projected to reach $4.53 billion by 2025, with a CAGR of 4.2% from 2020 to 2025.
