What happens to a non dimmable lamp if used on a dimmer?
If you use a non-dimmable Compact Fluorescent Lamp (CFL) in a circuit controlled by a dimmer switch no damage will be done but the CFL will stay bright when the dimmer is turned down whilst any other normal incandescent lamps wired into the same circuit will go dim in the normal way.Dimmable Compact Fluorescent Lamps are now available, for example in the Megaman range of CFLs. For more information see the Related Link shown below.Incandescent dimming uses any incandescent lamps and an incandescent dimmer.To dim fluorescent lamps usually requires use of fluorescent dimmers AND fluorescent dimmable ballasts. If these two components do not match, dimming will not work.The fluorescent lamps themselves are the same whether you put them in a standard (nondimming) ballast or a dimmable ballast.If your dimmers are not dimming the CFLs they are either not fluorescent dimmers or, more likely, your ballast in the light fixture is not a dimmable ballast.
What is an electrical ballast?
Firstly, there are a few meanings for the word ballast, and they are used in different contexts.In an electrical context:Electrically, It adds resistance to limit the current. In a fluorescent light fitting, the ballast adds resistance. Once the lamp conducts, it presents a very low resistance to the circuit and would draw too much current. The ballast coil also has reactance and provides a back emf pulse, to enable the lamp to fire (conduct) when it is interrupted by the starter.In an a shipping context:Ballast is used in ships and submarines (both new and old) to provide stability to the vessel within the water. Normally the trim of a boat in the water will differ whether it carrying a cargo or not, if the ship is lighter and higher in the water it is more inclined to roll from side to side in heavy weather. In order to prevent this ballast tanks are used in ships, these are then filled with seawater in to make the ship heavier (lower) in the water and less prone to tilting. Before the ship takes on cargo the tanks are pumped out making the boat "ride" higher in the water. Earlier wooden vessels also used ballast, but would use stones, rock or bricks for this purpose.In submarines, ballast tanks are flooded with water or purged using compressed air in order to maintain neutral buoyancy, or to allow the submarine to ascend or descend.In hydraulics/ irrigation terms:Ballast tanks (sometimes called buffer tanks) are used in irrigation and plumbing systems to provide a buffer between supply and demand systems. A simple example of this is the water tank of your toilet. The system, when flushing requires a fairly substantial amount of water, the mains water supply of a typical house does not have this volume all at once, so the water is stored in a small ballast tank. When you press the flusher a larger volume of water that can normally be supplied by the house water supply is release - giving you a clean bowl.
Do all cells in your body look identical and why?
This is because different genes are switched on or off in different cells. For example, the cells which develop into red blood cells have the gene for making hemoglobin (the red, oxygen-carrying pigment) switched on. Other cells have this gene switched off.
How you can calculate the ampere for fluorescent lamp with use VA?
To calculate the amperes for a fluorescent lamp using VA (volt-ampere), you can divide the VA rating by the voltage of the lamp. The formula is: Amperes = VA / Voltage. For example, if a fluorescent lamp has a VA rating of 60 VA and operates at 120 volts, the amperes would be 0.5A (60 VA / 120V).
What is a Compact Fluorescent Lamp or CFL and how does it work?
A 3-way incandescent bulb works by having two separate filaments for the first two levels of brightness. For example, a 30-70-100 bulb will have a 30 watt filament and a 70 watt filament. The 3-way switch then turns on either the 30, the 70, or both - giving the 100 watts full brightness. (This is why a 3-way incandescent bulb usually burns out the most commonly used brightness level first.) A 3-way compact fluorescent, using the same simple 3-way switch, will either have two separate fluorescent tubes, one for each of the first two brightness levels (unlikely), or it will adjust the brightness electronically through an internal voltage (or other) adjustment based on which position the 3-way switch is set at. This is only an approximation - additional details would be interesting.
What the difference between ballast and transformer?
A transformer changes the amperage and / or voltage. It literally "Transforms" electrical energy. A ballast is like a capacitor. Think of a ballast as a short-term battery. It stores power then releases it as needed. A common example of a ballast is on fluorescent lights. Initially, a fluorescent light needs a big blast of energy to excite the gas molecules into emitting photons (light). Then it only needs a small amount of energy to keep the gas molecules in an excited state. However, that power has to be of consistent amperage and voltage. The ballast is designed to do that. The electrical ballast stores energy in the same way that a water ballast stores water for stability. Because the electrical ballast stores far more power than the device it regulates requires, it too provides a kind of electrical stability. That's why you often see a fluorescent light flicker or "lose stability" when the ballast starts to go bad. A transformer transforms voltage and amperage up or down. A ballast provides a stabile power supply.

What is the adverb of switched?
An adverb is a word that modifies a verb. In the case of the verb switched, an adverb example would be quickly, because it tells how something was switched.
Is fluorescent bulbs as it lights up an example of plasma?
yes
How energy efficient is a fluorescent bulb and how much does it cost to run one 5ft fluorescent bulb 9hrs a day for the average business year excluding weekends bank holidays etc in british pounds?
The formula is (bulb watts x ballast power factor) x hours / 1000 = kWhCost is simply kWh x gbpFor example: Your light bulb is 60 watts, evidenced by the writing on the bulb saying... 60 watts. However, fluorescent lights have a ballast, which is a type of transformer. Each ballast converts the input voltage to something usable by the fluor. bulb. In the case of modern electronic ballasts (vs. magnetic), the power factor ranges from .65 - 1.0. You can get this info from the manufacturers website. For this demonstration, we'll use .88, which is the standard power factor in the US for the big 3 ballast manufacturers.Next calculate your hours, for the energy industry, we accept 2080 hours for office buildings. This covers janitorial staff, weekend workers, etc.So, we have (60*.88)*2080/1000 = 5798 kWh ?? The answer I get is 109.824 kWh when using the above formula. Where did 5798 come from ??
Can color blind people see fluorescent colors?
I have partial colour blindness, and I see fluorescent colours as pale dessatureted colours. for example, where a normal person ould see a bright vivid fluorescent pink I see nothing but a pale salmon tone.
Which of fluorescent and florescent is spelt right?
The correct spelling of that word is fluorescent.Some example sentences with the word are:The fluorescent lighting in the office was broken.He wore a fluorescent vest when he cycled.Doctors have warned that working under fluorescentlighting for too long can cause eyesight issues and migraines.

Is the internet be descrided as a circuit switched network or packet switched network?
The Internet is packet switched, meaning each individual packet is routed from the source to the destination separately, and possibly through different paths. An example of a circuit-switched network would be the telephone network, where a connection from one end to the other is created and maintained until the call is disconnected.
