Inductance-related units for measuring magnetic flux

Inductance is the ability of a material to resist changes in the flow of current, creating a magnetic field in response. This phenomenon is fundamental in electrical engineering, especially when dealing with transformers, inductors, and motors. Whether it’s measured in henries or smaller subdivisions like millihenries, inductance governs how circuits respond to alternating current. It’s essential for controlling energy in systems and understanding the storage and release of electrical energy in magnetic fields.

Common inductance units

Henry (H): The SI unit of inductance, representing the amount of inductance needed to induce a voltage of one volt when the current is changing at a rate of one ampere per second.
Millihenry (mH): One thousandth of a henry (1 mH = 10⁻³ H), used for inductors in lower ranges.
Microhenry (µH): One millionth of a henry (1 µH = 10⁻⁶ H), used in high-frequency circuits.
Picohenry (pH): One trillionth of a henry (1 pH = 10⁻¹² H), used for extremely small inductances.
Kilohenry (kH): One thousand henries (1 kH = 10³ H), typically used for very high inductance values.
