    Electricity, lighting electricity is just a bai

    Fraction. You "paid more than 100 du electricity bills" last month, and you used air conditioners, refrigerators, or other electrical appliances. Otherwise, the line is leaking, please look for it.

    Any electrical appliance can not be calculated only by "power * time * days", because the line from the meter to the electrical appliance also consumes electricity, and the switch should also pay attention to the ash or putty (kitchen) on the switch, which consumes a lot of electricity.

    Your 18W lamp has not been turned off, 1 month, the theoretical electricity consumption is about 13 degrees, and the normal actual power consumption is 15 degrees. The 5W lamp has not been turned off, 1 month, the theoretical electricity consumption is about 4 degrees, and the normal actual power consumption is 5 degrees. The difference between the two is 10 kWh.

    If it is calculated as 30 days a month and 12 hours a day (7:00 p.m.-7:00 a.m.), it can save (18-5) * 12 * 30 1000 = kilowatt-hour of electricity per month.
