Ohm's law

Online Ohm's Law calculator allows determining the relationship between current, voltage, and resistance in electrical circuits.

For calculation, you will need to use separate fields:
- current is calculated in Amperes, based on voltage data (Volt) and resistance (Ohm);
- voltage is calculated in Volts, based on current data (Ampere) and electrical resistance (Ohm);
- electrical resistance is calculated in Ohms, based on current data (Ampere) and voltage (Volt);
- power is calculated in Watts, based on current data (Ampere) and voltage (Volt).
