If a light bulb has a mean of 1400 hours and a standard deviation of 100 hr what is the probability that the light bulb lasts between 1290 hours and 1530 hours?
It is 0.2325
How many kilowatts does a light bulb use?
Thsi depends on the light bulb specification. For example if you buy a standard 60W light bulb from your supmarket then this will consume 0.06kilowatts. Its simple just divide the wattage stated on the light bulb by 1000 to give you the kilowatts
How is electric power of a light bulb measured?
Since the light bulb is purely resistive (has very little reactance), you can just measure the RMS voltage across the light bulb (usually 120 V) and the RMS current going through the light bulb. Power (P) is:P = VRMS x IRMSwatts

How is a light bulb better for growing plants then a fluorescent?
A light bulb produces a more focused light output which can be beneficial for specific plant growth stages. It also generates less heat, allowing it to be placed closer to the plants without risk of damage. Additionally, light bulbs typically have a longer lifespan compared to fluorescent lights.
Why does a circular fluorescent light bulb not light up fully?
A circular fluorescent light bulb may not light up fully due to issues such as a faulty ballast, aging tube, or poor connection with the socket. These factors can lead to insufficient power reaching the bulb, causing it to not reach its full brightness.
What type of light is 20w energy saving bulb Halogen Indandecent neon fluorescent etc please help?

How much is a fluorescent bulb?
fluorescent light bulbs are usually from 9$-15$.
How often do fluorescent lights have to be changed?
Fluorescent lights typically last about 10,000 to 15,000 hours, which translates to approximately 3 to 5 years when used for about 8 hours a day. However, it's recommended to change them once every 1 to 2 years to ensure optimal brightness and efficiency.
What year was the fluorescent light bulb invented?
The fluorescent light bulb was invented in 1938 by George Inman, who improved upon earlier versions developed in the 19th century.
what is the long thin light bulb called?
The long thin light bulb is called a fluorescent tube or a fluorescent light bulb. It is commonly used in commercial buildings, offices, and schools for general lighting purposes.
What is the fluid in a fluorescent light bulb?
In a fluorescent light bulb there is usually a drop of mercury. That mercury vaporizes as the bulb warms up and it becomes gaseous, enhancing the electron interaction through the bulb, making it brighter.
How much energy does it take to run a 15w fluorescent light bulb for 24hrs?
To calculate the energy used by running a 15W fluorescent light bulb for 24 hours, you can use the formula: Energy (kWh) = Power (kW) x Time (hours). In this case, the energy consumption would be 0.36 kWh (15W x 24 hours / 1000).
Which is hotter a fluorescent light tube or a light bulb?
By far the hottest of the two light sources is the light bulb.
