Power (Watts) / Voltage (Volts) / Current (Amps) Calculator
Enter any two values to calculate the third, based on the formula: Power (W) = Voltage (V) × Current (A).
Calculation Results
Important Notes:
- This calculator uses the basic DC power formula. For AC circuits, power factor should also be considered (Real Power = V * I * Power Factor).
- Ensure the units are consistent (Volts, Amps, Watts).
- Always use appropriate safety measures when dealing with electrical power.
Understanding the relationship between electrical power, voltage, and current is foundational for anyone working with electronics, electrical systems, or even household appliances. This crucial relationship is governed by a simple yet powerful formula: Power (Watts) = Voltage (Volts) × Current (Amps). While the formula itself is straightforward, calculating these values manually, especially when troubleshooting a circuit, designing a new system, or simply trying to understand energy consumption, can be time-consuming and prone to errors. For electricians determining appropriate wiring, electronics hobbyists selecting components, or students learning about Ohm’s Law, the need for quick and accurate calculations is constant. Miscalculations can lead to inefficient designs, damaged equipment, or even safety hazards. This is precisely why the WorkToolz Power / Voltage / Current Calculator is an indispensable resource, offering a precise, reliable, and incredibly simple way to derive any of these three electrical values when the other two are known.
