Which of the following defines the relationship between watts, volts, and amps?

The relationship between watts, volts, and amps is defined by the formula that states watts equal volts multiplied by amps. This formula comes from electrical power calculations, where power (measured in watts) is the product of voltage (measured in volts) and current (measured in amps).

Using this equation, one can determine how much power is being consumed or produced in an electrical circuit. For example, if you know the voltage supplied to a device and the current flowing through it, you can easily calculate the power output or consumption.

When considering the other choices, it's evident they do not adhere to the established electrical principles. The first option incorrectly suggests that power is calculated by subtracting current from voltage, which does not reflect the relationship between these electrical quantities. The second option implies a division operation, which inaccurately represents how these metrics interact. Lastly, adding volts and amps does not yield a meaningful power measure; voltage and current cannot simply be summed in this context, as they are distinctly different units representing different physical properties. Therefore, the correct statement is that power is indeed the product of volts and amps.
