Resistance Calculator

This calculator helps you determine electrical resistance using Ohm’s Law. It is commonly used in electronics, circuit analysis, and engineering applications.

Ohm’s Law Formula

Resistance (R) = Voltage (V) / Current (I)

Why It Matters

Resistance calculations are important for controlling current flow and protecting electronic components.

Example

If voltage is 10 V and current is 2 A, resistance is 5 Ω.

How to Use

  1. Enter voltage (volts)
  2. Enter current (amps)
  3. View calculated resistance instantly
