How do you determine watts?

To determine watts, the correct calculation involves multiplying the current (in Amperes) by the voltage (in Volts). This relationship is derived from the fundamental electrical power formula: Power (Watts) = Voltage (Volts) x Current (Amps).

In practical terms, when you know the voltage supplied to a device and the current it draws, you can easily calculate the total power consumption in watts. This is particularly important in water treatment facilities where understanding the power usage of pumps, motors, and other electrical equipment is necessary for efficiency and operational cost management.

The other options do not correctly represent the relationship needed for calculating power in watts. The choice that sums Amps and Volts does not yield a meaningful metric for electrical power and is not a recognized formula in electrical engineering. Moreover, dividing watts by amps gives you voltage, which doesn't directly relate to the calculation of power. The formula involving Ohms does not apply here because it's not part of the basic power calculation. Hence, the multiplication of Amps and Volts clearly provides the correct method to determine watts.
