Inductance Calculator
Calculate inductance using V = L(dI/dt). Enter voltage, current change, and time change to find inductance.
How to Use the Inductance Calculator
- Enter the induced voltage in volts.
- Enter the change in current in amperes.
- Enter the time interval over which the change occurs in seconds.
Quick Reference
| From | To |
|---|---|
| Small coil | 1–100 μH |
| Power inductor | 1–100 mH |
| Transformer primary | 0.1–10 H |
| 1 V, 1 A/s | 1 H |
Use Cases
- •Designing inductors for power supplies.
- •Analyzing LC and RLC circuits.
- •Physics problems on electromagnetic induction.
Formula
V = L × (dI/dt), so L = V × dt / dI, where L is inductance (H), V is voltage (V), dI is current change (A), dt is time (s).
Frequently Asked Questions
What is inductance?
Inductance is the property of a conductor that opposes changes in current. It is measured in henrys (H).
What produces inductance?
A changing current through a conductor creates a magnetic field, which induces a voltage opposing the change (Lenz's law).
