Formula

The formula to calculate Energy Consumption (kWh) is:

\[ E (\text{kWh}) = \frac{P (\text{W}) \times H (\text{hours}) \times D (\text{days})}{1000} \]

Electricity Consumption Definition

Electricity consumption is the amount of electrical energy used by a device or system over a specific period. It is typically measured in kilowatt-hours (kWh), which represents the energy consumption of a device using 1,000 watts for one hour.

Example Calculation

Let's assume the following values:

Using the formula:

\[ E = \frac{100 \times 5 \times 30}{1000} \]

\[ E = 15 \text{ kWh} \]

The Energy Consumption (kWh) is 15 kWh.
