Easy: How to Calculate Amps from Watts + Examples

Determining the electrical current in amperes requires knowing the power in watts and the voltage of the circuit. The calculation varies based on the type of current, whether it is direct current (DC) or alternating current (AC). For DC circuits, the amperage is simply the wattage divided by the voltage (Amps = Watts / Volts). In an AC circuit, the calculation is more complex as it requires also knowing the power factor. For example, a 100-watt light bulb operating on a 120-volt DC circuit draws approximately 0.83 amps (100/120 = 0.83). For an AC circuit, one would use the formula Amps = Watts / (Volts x Power Factor).

Understanding this calculation is essential for various applications, including electrical design, safety, and troubleshooting. Accurate assessment of electrical current prevents overloading circuits, reducing the risk of fires and equipment damage. Historically, the relationship between power, voltage, and current was established through the work of physicists like Andr-Marie Ampre and Georg Ohm, forming the foundation of modern electrical engineering.
