Everybody help me calculate my computer s electricity bill

Your electrical appliances only have a notebook and a lamp, according to your test results, the power of the notebook is 118w, which is already large compared with the usual power of the notebook, in addition, your lighting does not know whether to use a rod tube or a bulb, if it is an ordinary lighting power 40w is enough, the total power consumption is 118 + 40 = 158w, according to the maximum power consumption in a day, the computer does not stop for 24 hours, and the lighting is calculated for 12 hours of working time, and the total power consumption of a day is 118* 24 + 40 * 12 = 3312w, a month's power consumption is 3312 * 30 = 99360w = degrees, according to one kilowatt-hour of electricity, money calculation (generally electricity in yuan per kilowatt-hour, few landlords will give you power at the market price, the landlord should charge you more, but not more than one dollar per kilowatt-hour, this is my experience of renting a house) your total electricity bill for a month is yuan. Your landlord's electricity meter has gone more than 400 degrees, which is really shocking, brother, you live in a black store.

You're renting a house, right? If it's a rented house, listen to me and move out, then the meter is very likely to have been tampered with by the landlord. If you ask him, he won't admit it, I've encountered such a thing.

At first, I thought it was someone stealing electricity, but then I asked the teacher of the school's mechanical and electrical department to come over to help me see, and there was nothing to do, the teacher said that the meter had been passed.

Personal experience, I hope it can help you. Good luck

If you say that the power consumption of your computer is 118 watts, then you plan to use 24 hours a day, so you use electricity a day, 30 days a month, but only use less than 85 degrees of electricity, if your meter goes more than 400 degrees a month, then your home must be leaking, maybe someone else steals your electricity. Personally, I think that household electricity consumption of 400 kWh a month does not exist.

It depends on how many hours a day you drive! If the average computer is turned on for 8 hours a day and the power is 118 watts, the following formula can be used for the electricity consumption in a month: power consumption * daily use time * number of days in a month 1000, that is, 118 * 8 * 30 1000 = kilowatt hours in a month, calculated according to the local electricity bill

Yuan. Fluorescent lamps typically consume 40 watts each, unless you have a lot of lights in your home and turn them on at the same time. The last digit of my home appliance meter is one decimal place, I don't know if it's the same as your home.

The laptop will consume more power when playing games and opening a large number of programs, but it will basically not exceed 200 watts, even if it is turned on for 14 hours a day, it will only be 80 kilowatt-hours of electricity in a month, 400 degrees is too exaggerated.

One kilowatt-hour of electricity is one kilowatt-hour, your computer power consumption is 118 watts, about eight hours of electricity, if you use eight hours a day, a month is calculated as 30 days, you use 30 kilowatt-hours of electricity a month, if calculated per kilowatt-hour of electricity, your monthly electricity bill should be about 15 yuan. Of course, do you sleep and go to work without turning off the computer, or do you have other household appliances at home, such as cooking induction cookers, which are all power-hungry appliances.

8 kilowatt-hours of electricity, one kilowatt-hour of electric yuan, that day needs 4 yuan.

When the computer is running normally, it is about 280 350W, and it takes about 1000W to use one kilowatt-hour (1000W = 1 kWh per hour) for 3 hours, and if it is turned on for 24 hours, it is 8 kWh of electricity per day.

Ways to save electricity with a computer:

1. Change the power settings on the computer to save power.

2. Click the "Menu Bar" on the desktop to see the "Control Panel" and open the Control Panel.

3. Because it is to save power on the computer, you need to set the power supply, and click "Power Options" in the big icon.

4. He changed the "preferred plan" to "energy saving, which can make the computer more power-saving."

5. Then click on the blue word "Change Plan Settings", turn "Turn off the monitor" and "Sleep state" to a shorter time as possible, and click "Save Modification".

6. Under Change Plan Settings, click "Change Advanced Power Settings".

7. After entering the settings page, double-click "Hard Disk" and change "Never" to mold failure to set a shorter time point.

8. Double-click "Sleep" again, and change the "Never" Zen school to a time point you want to set, which can be more power-saving on the computer. Finally, save the changes. <>

Let's put it this way, the power consumption of the computer per hour is almost the kilowatt-hour of electricity, which can be calculated as 4 hours of electricity, which is less than 5 kilowatt-hours of electricity per day, and how many days in 3 months can be calculated by yourself.

The power of the floor fan can be ignored, 2 months can be counted as 20 degrees, and the induction cooker that does not consume electricity is 2 degrees per hour, and you know how many hours it takes.

700 degrees for 4 months, an average of less than 200 degrees per month, is also normal for the appliances in your dormitory. You must know that the power consumption of an induction cooker can be more than that of a 2P air conditioner.

Four hours of electricity, two degrees a day. 2*30*075=45 blocks.

One kilowatt hour = 1 kilowatt hour.

40W one-hour power consumption = kW * 1 hour = kWh (kWh) 24 hours power consumption = kWh (kWh).

If you drive for a month, the power consumption = kilowatt-hours = kilowatt-hours (kWh) I calculate it this way, you understand?

2. Correct, 40W is power, not voltage.
