Calculadora da Lei de Ohm — Formula

## How Ohm's Law Works

Ohm's Law links voltage, current, and resistance.

### Formula

**V = I x R**

Where:
- **V** = Voltage in volts
- **I** = Current in amperes
- **R** = Resistance in ohms

Rearranging gives **R = V / I** and **I = V / R**. Power is **P = V x I**.
