What is the resistance of a standard 120-V, 60-W lightbulb

A light bulb is rated 150W for 220V ac supply of 60Hz. Calculate (i) the resistance of the bulb; (ii) the rms current through the bulb (a) What is the resistance of a lightbulb that uses an average power of 75.0 W when connected to a 60.0-Hz power source having a maximum voltage of 170 V? (b.. A standard 60-watt incandescent bulb puts out about 820 lumens. That translates to a 60-watt incandescent bulb producing 13.67 lumens per watt. One of the better CFLs on the market, the GE Reveal Bright from the Start light bulb, uses 15 watts to produce 740 lumens. That bulb has an efficiency of 49.33 lumens per watt. That's a nice improvement

The resistance of a light bulb filament is effected by both length and cross-sectional area. Thicker wires have less resistance. A 120-Watt bulb has a greater current and a smaller resistance. Thus, a 120-Watt bulb must have a thicker filament than a 60-Watt bulb (assuming the lengths of the filaments are identical) Note - A light bulb rated at 60 watts at a voltage of 120 volts has a different filament resistance to consume 60 watts instead of 100. The filament in a 60 watt bulb has a resistance of 240 ohms as compared to 145 ohms for a 100 watt bulb. The above assumes that the voltage source is constant at 120 volts

The term 60-Watt equal has little to do with any kind of wattage correlation; a 60W equal LED may use as little as 8 Watts to operate. It simply means that the bulb, whether CFL or LED, is able to produce as much light as a 60-Watt incandescent You can ignore the reference to 60 watts. That's shorthand for Produces approximately the same lumens as a 60-watt incandescent bulb. What is important is the power the bulb uses—in this case, the 14 or 15 watts A lumen of 750 lumens equal to a 60-watt Bulb calculates the luminosity of the LED bulb. If you choose to get mood light, pick a softer, fewer lumens light bulb. But a great fit is a higher-powered lamp if you're trying to illuminate the night after the sun goes down

Calculate the resistance of the filament in a light bulb that carries 0.4 A when 3.0 V is impressed across it. A current of 0.5 A flows in a 60 W light bulb when the voltage difference between the ends of the filament is 120 V. A 30 kΩ resistor rated at ½ Watt will be damaged if a current flow of 4.5 mA is flowing through it. T/F The P.F.A. coating (Teflon) around the bulb is a very unique material that combines extreme temperature resistance with high clarity, excellent adhesion and high impact strength. Operating at 60 watts, it has a medium (E26) base and an average life of 8,000 hours. When safety is a concern, shatter resistant light bulbs are the only option Conversely, low wattage bulbs, which are dimmer, have thinner filaments that present a higher resistance, and for a common voltage, would draw a smaller current.

SURVEY . 30 seconds . Q To answer your first question: A 100W light bulb has lower resistance because as long as the light bulb resistance is higher than the wire resistance, you can take advantage of the equation P=I squared R. Just decrease the resistance a little and the current is increased. Since the increased current is squared you get a lot more power One side of the 120 AC line to a 100 watt light bulb...the other side of the bulb to a 14.6 ohm resistor.....they say to make up the resistor by paralleling 5 of them...3 of which are 68 ohm 1 watt....the other 2 are 82 ohm 1 watt.....then the other end of the resistor goes to rod #1..the other side of the AC line goes to the farthest rod....

To reduce the heat emitted by regular incandescent and halogen bulbs, use a lower watt bulb (like 60 watts instead of 100). Fluorescent light bulbs use an entirely different method to create light. A key factor is to use materials with a high thermal conductivity to move heat away from the junction as quickly as possible A one hundred watt bulb has extra resistance than a 60 watt bulb does (use Ohm's regulations). something with extra resistance has extra means to end electron/ proton bypass than one with lesser resistance. by way of fact it has extra resistance, further and extra warmth gets accumulated, and the temp will enhance... this reasons extra easy to be released What is the resistance of a 60 Watt light bulb that allows 500 mA to flow when 120 V is applied to it? 5.

Resistance of a lightbulb? Physics Forum

With a 60-Watt light bulb, for example, you are forcing 0.5 amp of electrical current (the water) through the filament (the hose) with 120 Volts of pressure. The current meets the resistance of the filament, causing the filament to become hot and glow The Centennial Bulb has a carbon filament in a vacuum bulb. It was made by the Shelby electric company in the late 1890s. The glass bulb appears to be a little dark with a red filament (low temperature) glowing inside. It was originally labeled a 60 Watt bulb. Today, it consumes only 4 Watts Find the number of watts (sometimes it can be found on the base of the bulb in small print). Divide the watts by the voltage. The voltage will depend on where the bulb is being used. In the US, voltage is usually 120 for the wiring to a household light fixture. For example, if the bulb is 12 watts: 12 divided by 120 = .1 A (one tenth of an amp) Start by finding the wattage of each light bulb. This is often printed right on the light bulb or the original package. The average A19 incandescent light bulb uses 60 watts of electricity, which is a good starting point if the bulb is inaccessible. To find the total wattage of a fixture, add the wattage of each light bulb together

For example, a 100 watt bulb is brighter than a 60 watt bulb. Lumens is the unit of measurement for that brightness. For example, I believe that a 60 watt bulb gives 1300 Lumens of light. As where 100 watt bulb gives 1450 lumens. But, it is the wattage that determines the lumens that are.

60 Watt, 120 Volt?? easy question for you - DoItYourself

A 60 Watt 220V bulb means that it will consume 60 Watts when the voltage across it is 220V. In such a case the current flowing through it will be given by I= W/V = 60/220 = Amperes. And the resistance of the filament will be W/I^2= (60 * 220/60* 220/60) = 806.67 ohm In other words, 100 Watt bulb has less resistance and 80 Watt bulb has a high resistance. When bulbs connected in Series. We know that current in a series circuit is same at each point mean both bulbs getting the same current and voltages are different. Obliviously, the voltage drop across higher resistance bulb (80W) will be more The visible light output verses power would also be interesting measurement. At 20 Watts almost no light is visible.

How to solve: The typical resistance of the tungsten filament of a 60 watt incandescent light bulb when it is turned off is 24 ohms and its.. A 60-watt light bulb carries a current of 0.5 ampere. The total charge passing through it in one hour is: A. 120 C . B. 3600 C . C. 3000 C . D. 2400 C . E. Of the following the copper conductor that has the least resistance is: A. thin, long and hot . B. thick, short and cool . C. thick, long and hot . D. thin, short and cool . E When you see 60W equivalent on LED bulb specifications, it means that that specific bulb emits the same amount of light as a 60-watt incandescent bulb. What's important to notice though is that the LED bulb's actual wattage will be significantly lower than the incandescent light bulb's wattage. In fact, LED bulbs consume about 80 percent. So, I bought a lamp that has a max rating of 60 watts for regular bulbs, 21 watts for CFL bulbs, and 15 watts for LED bulbs. I don't really understand that, particularly given that the more efficient bulbs generate less waste heat

31. To increase the brightness of a desk lamp, a student replaces a 60-watt light bulb with a 100-watt light bulb. Compared to the 60-watt bulb, the 100-watt bulb has less resistance and draws more current; less resistance and draws less current; more resistance and draws more curren Watt can not be completely expressed in terms of degree. But 60 watt usage for one hour is equal to 60 watt hour energy and the surface temperature is near about 200 degree Fahrenheit . It is just like comparison of a 500 watt best coffee maker consumes same energy as the light bulb

For example, you can use a 100 Watt equal LED bulb to replace a 60 Watt incandescent bulb because the LED bulb only uses 15-20 Watts, well below the maximum rating of the fixture. You cannot use a 100 Watt incandescent bulb, because the bulb would draw more power than the fixture can handle So, when purchasing antique bulbs for your home, be aware that a 60-Watt antique bulb will emit closer to 400 Lumens, whereas a 60-Watt standard A19 incandescent bulb will emit closer to 800 Lumens. But remember, these bulbs are for accent lighting, not task lights or to replace overhead lights

These rapid-fire swings in voltage create electromagnetic resistance in the bulb, which can cause things to vibrate and buzz. bulbs like the Cree 60-watt replacement variance in the light. So to go back to our original example, to brighten up a room, it would be dangerous to place a 100-watt incandescent into a lamp rated only for 60 watts. However, you could use a 14-watt LED or CFL bulb that's marked as equivalent to 100 watts, which would give out the same amount of light while staying far below the maximum wattage
