Question

How can you calculate the electricity bill for your home?

Answer 1

The electrical energy used in homes, shops, and industries is measured in kilowatt-hours (kWh). The electricity meter installed in our home records the electrical energy consumed by us in kilowatt-hours.

1. The kilowatt-hour (1kWh) of electrical energy is commonly known as ‘1 unit’ of electricity.
2. Our electricity bill shows the electrical energy consumed by our household in a month in ‘ kilowatt hours’ or ‘units’ of electricity.
3. One unit of electricity (or 1kWh) may cost anything from Rs 5 (or even more). The rates of electrical energy vary from place to place and keep on changing from time to time.
4. Suppose an electric appliance at our home has consumed 200 kWh electric energy in a month and the cost of 1 unit is Rs 5
5. The total bill for the month will be $200\times 5=Rs1000$.
