Enter the inductor current (amps) and the resistive load (ohms) into the Calculator. The calculator will evaluate the Voltage Spike.

## Voltage Spike Formula

VS = IC * RL

Variables:

- VS is the Voltage Spike (volts)
- IC is the inductor current (amps)
- RL is the resistive load (ohms)

To calculate Voltage Spike, multiply the inductor current by the resistive load.

## How to Calculate Voltage Spike?

The following steps outline how to calculate the Voltage Spike.

- First, determine the inductor current (amps).
- Next, determine the resistive load (ohms).
- Next, gather the formula from above = VS = IC * RL.
- Finally, calculate the Voltage Spike.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

inductor current (amps) = 5

resistive load (ohms) = 10
