What is the formula for calculating the amount of energy consumed?

The formula used to calculate the amount of energy consumed is indeed Energy (kWh) = Power (kW) × Time (hours). This formula directly relates energy to power and time, which are fundamental concepts in understanding energy consumption in electrical systems.

In this context, power is measured in kilowatts (kW), which indicates the rate at which energy is used or produced. Time is measured in hours, providing a duration over which this power is being consumed. When you multiply these two factors, you get the total energy consumed over that time period expressed in kilowatt-hours (kWh), a common unit for measuring energy usage in electrical applications.

This approach is consistent with the basic principles of electricity and helps in calculating energy costs for consumers, enabling them to understand their energy usage better and make informed decisions about their consumption patterns.
