Inductance is the tendency of an electrical conductor to oppose a change in the electric current flowing through it. It does this by creating a voltage (electromotive force) across the conductor.
The concept was coined by Oliver Heaviside in February 1886. The SI unit for inductance is the Henry (H), named after Joseph Henry.
The relationship between induced voltage and current change is defined by the following formula:
Where:
While the Henry (H) is the standard unit, it is quite large for most electronics. We typically use prefixes to measure smaller values:
Below is a quick reference for converting between the most common inductance values.
| Unit | Value in Henry (H) | Conversion Example |
|---|---|---|
| Picohenry (pH) | H | 1,000 pH = 1 nH |
| Nanohenry (nH) | H | 1,000 nH = 1 H |
| Microhenry (H) | H | 1,000 H = 1 mH |
| Millihenry (mH) | H | 1,000 mH = 1 H |
