Enter the power in watts and the time in hours into the calculator to determine the energy in watt-hours. This calculator helps in estimating the energy consumption of electrical devices.
Energy Consumption Formula
The following formula is used to calculate the energy consumption in watt-hours.
E = P * H
Variables:
- E is the energy consumption (watt-hours)
- P is the power (watts)
- H is the time (hours)
To calculate the energy consumption, multiply the power of the device by the time it is operated.
What is Energy Consumption?
Energy consumption is the amount of energy used by an electrical device when it operates. It is typically measured in watt-hours or kilowatt-hours for larger consumption. Understanding energy consumption is crucial for managing electricity usage and reducing energy bills.
How to Calculate Energy Consumption?
The following steps outline how to calculate the Energy Consumption.
- First, determine the power of the device (P) in watts.
- Next, determine the time the device is operated (H) in hours.
- Next, gather the formula from above = E = P * H.
- Finally, calculate the Energy Consumption (E) in watt-hours.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
Power of the device (P) = 100 watts
Time the device is operated (H) = 5 hours
