How much does it cost to burn 7.5 watt night light bulb?
The bulb uses 7.5 watt-hours each hour, or 90 watt-hours if left on for 12 hours. 1 unit of electricity would be used in 11 days at 12 hours per day.
How much eletrical energy in kilowatt hours would a 60.0 w light build use in 60.0 days if left on steadily?
To calculate the energy usage of the light bulb, we first convert the power in watts to kilowatts (60.0 W = 0.06 kW). Then, we multiply the power by the time (0.06 kW * 60 days) to get the total energy consumed in kilowatt-hours. Therefore, the light bulb would use 3.6 kWh of electrical energy if left on steadily for 60 days.
Watt-hour a light bulb consumes 3600 watt-hours per day How many watt-hours does it consume in 4 days and 6 hours?
-9900
How many days is 00000924 light years?
1 light year is approximately equal to 5.88 trillion miles. So, 9,240 light years would be about 54.3 quadrillion miles. If we convert that to days (assuming a speed of light travel), it would take light around 1.52 million days to cover this distance.
How long does an average light bulb last?
Depending on the quality of their design - and the quality of the components used in their manufacture - compact fluorescent light bulbs have rated lifetimes between 4,000 and 12,000 hours of "actual in-use time" whilst they are switched on. These ratings are for use under ideal cooling conditions and the lifetimes can be greatly reduced if their miniature ballast circuits overheat,such as when the bulbs are used in fully enclosed and/or recessed lighting fixtures.
How many days the light bulb lasted?

Why life of a bulb ends after certain time span?
By bulb, it is assumed a light bulb is intended rather than a flower bulb or any other kind of bulb. Light bulbs burn out because they are engineered to do so. There would be less profit to the bulb manufacturer if he made bulbs to last longer, which he could if he wanted to. In the early days of bulb manufacture, a bulb was made which still continues to burn over 110 years later. See the link below for more information on the 110 year bulb.
How much does it cost to burn 7.5 watt night light bulb?

How long does a normal light bulb last?
A flourescent light bulb lasts between 6000 to 18000 hours.
How many days did it take Thomas Edison to invent the light bulb?
He invented the incandescent light bulb and it took him 12 years.
What is now days light bulb filament made out of?
tungsten
If I Leave light on for 2 days straight?
You cannot leave it becuase the bulb will burn out and then probably do some damage to your house. You can if you close the lights after a few hours then turn it on again. Good luck!
How many days did Edison's best light bulb stay lit?
Edison's best light bulb stayed lit for around 40 hours. This experiment took place in 1879.
How long will a fruit power a light bulb?
The duration that a fruit can power a light bulb will vary depending on the type of fruit and the size of the bulb. Generally, fruits can power a simple LED light for a few hours to a few days.
Which was invented first the light bulb or telephone?
In those days they used oil lanterns i think......
How the light bulb works in old days?
the bulbs store a lot of energy inside itself before passing the filament and when they unscrewed it, it would stay on for quite a while
