What is the formula for calculating watts?

The formula for calculating watts is based on the relationship between voltage, current (amps), and power. Specifically, watts are defined as the product of volts and amps. This is derived from Ohm's Law and the power equation in electrical engineering, which states that power (in watts) is equal to the voltage (in volts) multiplied by the current (in amps) flowing through a circuit.

This relationship is fundamental in both electrical theory and practical applications, such as determining the power consumption of electrical devices. By using this formula, you can easily calculate how much power a device needs to operate when you know both the voltage and the current.

The other options either misstate the relationship or suggest operations that do not yield the correct measure of power. Understanding this core power calculation helps in various scenarios, such as designing electrical circuits or troubleshooting electrical equipment.
