Does a lamp with a thick filament draw more current or less current than a lamp with a thin filament?
A lamp with a thick filament will draw more current. What restricts the current flow in the filament is the resistance of the filament which increases as the temperature of the filament increases. A thin filament requires less energy to get heated up that a thick one so less current to achieve threshold resistance. Also a thick filament provides a broader path for current so there is less resistance per increase in degree centigrade. For these two (closely related but distinct) reasons it will require more current for the filament to get heated up to threshold resistance.
How are CFL light bulbs better than regular light bulbs?
A CFL uses 65% less energy and can reduce your power bill as well.A longer answerSince major improvements in the design of Compact Fluorescent Lamps (CFLs) from 1990 onwards, by using a CFL light bulb 80% energy of the energy can be saved compared to the energy that is needed to produce a given amount of artificial light using conventional incandescent filament bulbs.In other words, to produce the same amount of visible light, a modern CFL uses only 1/5 (one fifth) of the power that an incandescent filament bulb uses.For example, a 20 watt CFL bulb produces similar light to a 100 watt incandescent filament bulb and a 30 watt CFL matches the light output of a 150 watt incandescent filament bulb.CFLs also have a much longer useful life-span, thus avoiding the need to change them as often as incandescent light bulbs.Another opinionThere are issues with the additional power used to manufacture CFL bulbs and the toxic chemicals inside these units.But, whilst they certainly do save energy for the end user, their drawbacks are that they probably use more energy overall and their manufacture causes more pollution.
Boy's are better in math than girls?
Boy are better in math than girls?
Who is better at the stroop effect boys or girls?
Girls are better than boys because they developoed faster than the boys did
Why The lightbulb is jophef swans invention why does Thomas Edison get all the credit?
Because Thomas Edison made it PRACTICAL, by discovering a filament that would last more than a few seconds.
Why Led bulb are better than filament bulbs for maximum reduction in the consumption of electrical energy explain?
LEDs produce visible light and not heat. Filament bulbs use much of their energy to produce heat. The LED bulb produces more light per watt consumed.
What are some advantages for having LEDs as bike tail lights?
LED lights are bright and use much, much less electricity than incandescent lamps.
LED lights are being used everywhere from down lights to head lamps of automobiles Are they provide adequate light as compared to traditional incandescent bulbs?
Yes, they provide as much light as the incandescent bulbs, thought some may vary according to their own type. But there's no other way that incandescent bulb can be compared to LEDs, because LEDs are way better than the old traditional bulbs.
Can light bulbs contain more than one filament?
Yes, automotive bulbs have more than one for turn and tail lights. 3 way bulbs in house lamps have 3.
How do LED displays work?
Light emitting diodes (LEDs) do not have a filament, like other bulbs do. They emit light by moving electrons inside the bulb. LED displays use up less energy than other displays.
Difference between tungsten lamps and carbon lamps?
tungsten lamp has got inert gas argonsometimes iodine is added to improve intensity carbon filament produces less light than tungsten lamp but it radiates much less energy in the form of heat waves
When you turn on your headlights in your 1997 freightliner century your driver side marker lights brighten and wont flash if you signal left but when lights are off all signals and brake lights work?
Did you replace these with LED bulbs, by chance? If so, you need to add resistors to the wiring in order for them to function properly. LEDs draw much less amperage than incandescent lights do, not to mention that all of the LEDs in an LED bulbs run on the same circuit, whereas a dual filament incandescent bulb has separate circuits for each filament.
What are the advantages of having LEDs for bicycle taillights?
LEDs use much less energy than other alternatives.
Is it a myth that leaving compact fluorescent lamps on rather than switching them off and on when needed uses more energy and is worse for the environment?
Leaving the lamps on 24/7 uses more energy than turning them on only when needed. It is equally true to say: A) It is not a myth that leaving incandescent filament lamps on 24/7, rather than switching them off and on when needed, uses more energy and is therefore worse for the environment. B) Using incandescent filament lamps instead of compact fluorescent lamps always uses more energy and is therefore worse for the environment. This remains true whether they are left on 24/7 or switched on and off when needed. If you switch the light off and on once each minute (or less), then there might be a case for leaving them on. Not only will they last longer, but the power lost to get them up to temperature will be reduced.
Is Led lumen better than metal halide lamps?
Metal Halide lamps produce many more ANSI lumens than an LED lamps. However, given this fact, many manufacturers are focusing their production on LED technology because they produce light that lasts 4 to 10 times longer, and they do not get hot like metal halide lamps.
Difference between SMD and DIP lighting?
In brief,SMD lighting is better technology and better quality than DIP lighting. In a LED light bulb,SMD LEDs are soldered on aluminum-substrate PCB while DIP LEDs is on a fiber glass PCB. Therefore,SMD light gets better heat dissipation to lower lumen depreciation and longer life.
Who is better alex or lampard?
Lampard is,because he has more experience than alex.I'm not a Chelsea supporter,but I would say lamps.
