Ohm’s Law Calculator

Calculate Voltage, Current, or Resistance using Ohm’s Law.

Voltage: \( V = I \times R \)
Current: \( I = \frac{V}{R} \)
Resistance: \( R = \frac{V}{I} \)

Step 1: Select Variable and Enter Parameters

Select What to Calculate:

Voltage Current Resistance

Current, \( I \) (A):

Example: 2 A

Resistance, \( R \) (Ω):

Example: 5 Ω
