This tool calculates the current (I) in **Amperes**. Enter the values of

- Resistance in
**Ohm** - Voltage in
**Volt**

**Formula**

**I = V/R**

This is also known as Ohm’s law which states that *the current through a conductor (I) with a constant resistance (R) between two points is directly proportional to the voltage (V) across the two points*.

**Example Calculation**

For a voltage value of **5 Volt** and resistor value of **2 ohm**, the current through the resistor is **2.5 Amperes** or Amps.
