How much does it cost to turn on all the lights in a 120 square meter house for a day?

Look at your lamp is a fluorescent lamp.

Or other lights, if all the lights of the 120-square-meter house are turned on, the power consumption is about two degrees a day, and the electricity consumption is about one dollar.

How much does it cost to turn on all the lights in a 120-square-meter house for a day, you need to see how many kilowatts all the lights in this house have, and one kilowatt is one kilowatt of electricity per hour, according to the current current electricity price yuan.

It depends on how many lights you have in your house. I don't think I would use ten dollars a day, if it were a normal lamp. Of course, if you're a power-hungry fixture, you can. About ten dollars.

Judging from your description, it is impossible to judge at all, because you only said the area, but did not say how many lights were installed, and did not say what the power of the lights was.

You said that if you turn on all the lights in a 120-square-meter house, how much electricity will be consumed a day, you can't solve this question for us. The lights in your 120 house, how many watts of lights do you have installed, this should be calculated according to time, according to your wattage.

Turn on all the lights in a 120-square-meter house to see how much electricity consumption? You should consider how many watts of lamps are used for your house's lights to calculate the electricity consumption cost for reference.

The lights in a 120-square-meter house are all turned on, and the electricity bill can be calculated according to the wattage of your lamp, and the electricity consumption per kilowatt is one kilowatt per hour.

Let you see what type of lamp you have installed, and how much is your lamp? I now use energy-saving lamps, which is estimated to be about one degree a day.

This power consumption has nothing to do with the size of your house. There is a relationship between the power of the light which can be turned on.

120 square meters of house, how much electricity consumption for lighting depends on how many lights you have installed, how much power lighting equipment you use, the difference here is big, but for modern life, lighting electricity is still a small head, with a large house of 120 square meters, still thinking about lighting electricity, incredible!

How many lights are there in your 120-square-meter room, but what is the power of no lights? There are ten lights, each with a power of 50 watts. Then you can use 1° electricity in two hours. It consumes 12° electricity a day and costs 6 yuan.

It depends on how many watts of light you have installed, if it is 1000 watts, it will be 12°C electricity in 12 hours.

How much electricity does it cost to turn on all the lights in a 120-square-meter house in a day? It depends on the wattage of your lamp. Under normal circumstances, there are only a few kilowatt-hours of electricity in a day, and it is only more than ten yuan.

About one kilowatt-hour of electricity a day, it is recommended not to do it, save a little.

Turn on all the lights in a 120-square-meter house, and the power consumption is not too much in a day, and at most a dozen kilowatt-hours of electricity will be wasted.

Turn on all the lights in a 120-square-meter house, how much electricity does it cost a day, you're going to have a 3°3 or 4° electricity, and somebody won't divide too much.

Turn on all the lights in a 120 square house, the electricity consumption of a day, it depends on how many lights are installed in your house?

An energy-saving incandescent lamp is about 20 watts, 10 hours a night, and if you calculate this by 2, it is a kilowatt multiplied by 10 hours is equal to a degree.

Household LED lamps are generally suitable for small power, and the rated current of low-power LED energy-saving lamps is 20mA, and the rated current is higher than 20mA can basically be counted as high power. The general power numbers are: etc.

The main brightness unit is LM (lumens), and the brightness unit of low power is generally MCD. These two units cannot be converted. As an emerging green, environmentally friendly and energy-saving light source, it is widely used in automotive lights, flashlights, lamps, etc.

It is recommended to install a downlight of about 3W in the bedroom, and the warm color temperature is the best; It is recommended to install about 5w in the living room below 20 square meters, and 7w in more than 20 square meters, because the illumination angle of the downlight is limited; Also pay attention to the number of installations.

63 kWh. The 180-square-meter house is old and only turns on the lights and uses 63 kilowatt-hours of electricity a month. Because with a 100-watt lamp, 3 rooms are estimated.

Turn on the lights in the morning and crack the dust for 1 hour, and Pai brother counts 6 hours from 6 o'clock to 12 o'clock at night, a total of 7 hours a day, and 3 rooms are 100 times 7 times 3 equals 2100 watts, which is the degree per day. 30 days per month is multiplied by 30 equals 63 degrees.

It can be turned on, and it doesn't cost electricity, which is generally about 20w, and it costs 2 cents a night.

Look at the power of the light. If it is a 60-watt incandescent lamp before, pressing 10 hours at night is the kilowatt-hour. If it is the current 3 LED 3 watt lamps, it is 90 watt-hours for 10 hours a night, which is about the kilowatt-hour of electricity. The specifics can be calculated.

Look at how big the wattage is, a kilowatt lamp, one kilowatt of electricity. 500 watts of electricity for two hours, down to the next level.

This problem is now high-tech, and you have to look at it more.

No matter how much power is saved, it doesn't cost much 2 jiao and 3 jiao.

The power of the lamp is a few watts, 1000 watts 1 hour 1 kWh, 100 watts 10 hours 1 kWh, 10 watts 100 hours 1 kWh,

Look at what kind of bulb it is, if it is an LED light, it can use 1 kilowatt-hour of electricity in 10 days. One kilowatt per hour. The LED is only about 5 watts.

If the room is turned on overnight, how much electricity it costs depends on how big your light is, one kilowatt hour of electricity.

It depends on how powerful your lights are.

The smaller ones consume less power.

The big ones consume more electricity.

The power of the lamp multiplied by time divided by one thousand is the degree.

It's just once, not much.

Look at how many watts (watts), one kilowatt-hour = one kilowatt-hour.

That is, a kilowatt electrical appliance is turned on for an hour and uses one kilowatt of electricity.

If it is a long light tube 60W - 1000 60 = hours) one kilowatt-hour.

If it is 12 hours a night, if it is 8 hours of sleep, only about half a kilowatt-hour of electricity is needed.

There is an energy-saving lamp with 12W or 20W that is already very bright (it is twisted, the same as the bulb) 12W 12 hours of electricity is about 8 hours.

A 100W bulb consumes more electricity when it is turned on for 24 hours. 100x24=2400w*h=degrees. It is calculated as follows:

W=PT (where W represents the value of the work done by electrical energy, P represents power, and T represents time). Kilowatt-hour is what is usually referred to as "degree", which is the unit of electrical work. Watts are the unit of power.

If you multiply the power by a time, then this result is work. The units of work are joules and kilowatt-hours, and the relationship between them is as follows: joules = 1 watt second.

kWh = 1 kWh Hour = 1000 Watt Hour = 1000 Watts 3600 Watts Seconds = 3600000 Joules. 3.Electrical power indicates how quickly and slowly electrical energy is consumed.

The physical meaning of kWh is the amount of electricity consumed by an electrical appliance with a power of 1kw working for 1 hour.

A 100W bulb consumes more electricity when it is turned on for 24 hours. 100x24=2400w*h=degrees. The calculation formula is: w=pt (where w represents the value of electrical energy to do special work, p represents power, and t represents time.)

genus). Kilowatt-hour is what is usually referred to as "degree", which is the unit of electrical work. Watts are the unit of power. If you multiply the power by a time, then this result is work. The units of work are joules and kilowatt hours, and the relationship between them is as follows:

1 joule = 1 watt second.

1 kWh = 1 kWh = 1000 watt hours = 1000 3600 watts seconds = 3600000 joules.

Electrical power indicates how quickly and slowly electrical energy is consumed.

The physical meaning of 1 kWh is the electrical energy consumed by an electrical appliance with a power of 1kw working for 1 hour.

1 kWh is equal to 1000 watts 100 watts = kWh.

So, is 24*degree= degree.

The electricity consumption of 120W lamp for 1 hour, (calculated according to one kilowatt hour per kilowatt hour) per kilowatt hour, the electricity cost of 120W per hour is about yuan.

120W should be kilowatt hours, and then multiplied by the unit price per electricity bill.

1 kWh is equal to 1000 watts 100 watts = kWh.

So, is 24*degree= degree.
