Electricity bills for domestic consumers are calculated based on energy consumption in kilowatt-hours (kWh) by multiplying the power rating of appliances by the hours of usage. Understanding energy consumption, power ratings, and cost calculation is crucial.
The calculation of an electricity bill for domestic consumers is based on the energy consumption measured in kilowatt-hours (kWh). This is obtained by multiplying the power of the appliance in kilowatts by the number of hours it is used.
For example, to calculate the cost of running a 0.200-kW computer for 6.00 hours per day for 30 days at a rate of $0.120 per kWh, you first determine the energy consumed (E = Pt) and then calculate the total cost.
Understanding energy consumption, power rating, and cost calculation is essential in determining electricity bills accurately for domestic consumers.
