Current Draw Calculator
Calculate electrical current draw (Amps) from power (Watts) and voltage (Volts) with our comprehensive calculator. Understand electrical load and circuit requirements for your devices.
Step 1: Electrical Parameters
Understanding Current Draw
Current (Amps) = Power (Watts) / Voltage (Volts). This formula calculates the electrical current required by a device based on its power consumption and the voltage of the electrical system.
Step 2: Additional Options
About Power Factor
Power factor is a measure of how effectively electrical power is being used. For DC circuits and purely resistive AC loads, the power factor is 1. For inductive loads like motors, it’s typically between 0.7 and 0.9. A lower power factor means higher current draw for the same power.

Current vs Power
Current Calculation Formula
Current (A) = Power (W) / (Voltage (V) × Power Factor)
To calculate current draw from power consumption, divide the power in watts by the product of voltage and power factor. For DC circuits or purely resistive AC loads, the power factor is 1.
