What else can I help you with?
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 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).
What is the average lifespan of a compact fluorescent bulb?
The average lifespan of a compact fluorescent bulb is typically around 8,000 to 10,000 hours.
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.
What is the swirly light bulb called?
The swirly light bulb is called a compact fluorescent lamp (CFL). It is a type of energy-efficient light bulb that produces light by using electricity to excite the gas inside the bulb to create illumination.
Which is hotter a fluorescent light tube or a light bulb?
By far the hottest of the two light sources is the light bulb.
The light-producing element in a fluorescent bulb is the?
The light-producing element in a fluorescent bulb is mercury vapor. When electricity passes through the gas, it emits ultraviolet light that then excites the phosphor coating inside the bulb, causing it to emit visible light.
