To calculate watts, the correct formula is watts equals amps multiplied by volts. This relationship is derived from Ohm's law and is fundamental in electrical engineering. Watts (W) are the unit of power, which quantifies the rate at which electrical energy is converted to another form of energy, such as heat or light.

When you multiply the current (measured in amperes or amps) by the electric potential (measured in volts), you are determining how much power is being used in a circuit. This is because each ampere of current that flows under a voltage contributes to the total power utilized in the system.

For example, if a device operates at 2 amps under a voltage of 120 volts, you would calculate the power consumption as 2 amps * 120 volts, which results in 240 watts. Understanding this formula is crucial for those in the field of mechanical technology and helps in managing and designing electrical systems efficiently.
