Step-by-step explanation:
For an electric company, it would make more sense to charge by the watt rather than by the joule.
The joule is a unit of energy, while the watt is a unit of power. Power is the rate at which energy is consumed or produced. When we use electricity, we are consuming power, not energy.
Charging by the joule would mean that customers would be paying for the total amount of energy consumed, regardless of the rate at which it was consumed. This would not be practical, as it would be difficult for customers to estimate how much energy they would need and how quickly they would consume it. It would also be difficult for the electric company to price its services in a way that accurately reflects the value of the electricity being consumed.
Charging by the watt, on the other hand, would mean that customers would be paying for the rate at which they consume electricity. This is more practical, as it is easier for customers to estimate their power needs and for the electric company to price its services based on the rate at which electricity is being consumed.
Therefore, it makes more sense for an electric company to charge by the watt rather than by the joule.
