Voltage Across Inductor Calculator

How to Use the Calculator

1. Enter the change in current (ΔI) in amps
2. Enter the inductance value (L) in henries
3. Enter the time change (Δt) in seconds
4. Click the "Calculate" button to compute the voltage across the inductor
5. Use the "Reset" button to clear all inputs and start over

Working Principle

The voltage across an inductor is determined by how quickly the current through it changes. The relationship is described by Faraday's law of electromagnetic induction:

V = L × (ΔI / Δt)

This means the voltage (V) is directly proportional to both the inductance (L) and the rate of change of current (ΔI/Δt).

Practical Applications

This calculator is useful for:

• Designing electronic circuits with inductors
• Understanding how inductors behave in AC circuits
• Calculating voltage spikes during current changes
• Analyzing energy storage in inductive components

Example

If an inductor with 0.5H inductance experiences a current change of 2A in 0.1 seconds, the voltage across it would be:

V = 0.5 × (2 / 0.1) = 10 Volts
