In order for a 30 volt 90 watt lamp to work properly in a 120 volt supply the required series resister in ohm is?
A 30 volt 90 watt lamp has 3 amps going through it. The series resistor also has 3 amps going through it, by Kirchoff's current law. The voltage across the resistor is 90 volts. With 3 amps, that is 30 ohms. (By the way... The resistor must be rated to carry 270 watts. That is a lot of power for a resistor.)
How many lumen in a 25 watt incandescent light bulb?
a 100W incandescent lamp emits 120 candela.lumen is the unit for luminous intensity per steradian ,an lamp emits in all directiontherefore a 16.25watt lamp contains 19.5 lumenAnswerThe lumen is the SI unit for luminous flux -which describes the output power of visible light expressed in photometric units. The ratio of a lamp's output luminous flux to its input power is termed 'efficacy', expressed in lumens per watt. The efficacy for incandescent lamp varies from 5-15 lumens per watt. So the output of a 16.25-W incandescent lamp will be between 80-245 W.
A 2000 watt heater connected to a 120 volt circuit will draw a current of?
Current (amps)=Watts/Volts =2000/120 =16.75 =16.75 amps
What is 60w light bulb?
a normal incandescent 60 watt light bulb uses 60 watts of electricity to produce 20 watts worth of light, and 40 watts worth of heat. It is more of a heat bulb than a light bulb. it is great if you can capitalise on the free heat, but if it is not cold in your house, turn it off. is there a better bulb? no. why are they ideal? cheap (as low as 10 cents for the el cheapos), never change shape/design/size/compatability, make pleasant light I could go on for an hour, but the best bulb is the cheapest.
Can a 6 volt battery light up a 4 watt bulb?
More voltage than required will light something such as a bulb. However, you have to consider such things as bulb longevity. Anything over 12 volts will illuminate a 12 volt bulb. If it's connected to an engine alternator and not a pure clean 12 volt power supply, ideally 13.5-14 volts is the voltage you're looking for to power this bulb. 16 volts will work, but it may prematurely burn the bulb out. That is, unless it is an LED. Even overpowered they will continue to burn bright, but not burn out, but it won't last as long as if it were connected to a true 12 volt supply voltage. But in the end, even an overpowered LED will last longer than an overpowered 12V incandescent bulb. It will definitely burn out prematurely if a higher than design intent voltage is supplied, however the hours. minutes, seconds lost may not be as high as people may assume them to be, from 12v to 16v is not such a jump especially in light of most automotive applications having output voltages up to 14.8v a car battery typically has 6 x 2.2v cells making 13.2v
A 60-watt 120 volt lamp requires morecurrrent than a 40 watt 120 volt lamp?
Yes. A 60W bulb has a higher resistance than the 40W buld. The extra resistance requires more current to light up the bulb. The fillament then glows brighter.
How many amps in a small table lamp?
A 120 volt table lamp with a 75 watt bulb will pull 0.625 amps. With a 100 watt bulb it will pull 0.833 amps. And with a modern fluorescent 13 watt bulb it will pull 0.108 amps.
Is 12 volt is enough for a 100 watt light bulb?
12 volts is enough for a 12-volt 100-watt light bulb. It would not be enough for a 120-volt or 240-volt bulb.
Can you use a 125 volt bulb in a 120 volt lamp?
Yes, the voltage listed on the bulb is the nominal voltage and it will work perfectly on a 120 volt circuit.
Can you use a 120 volt lamp where a 240 volt lamp was used?
No, the bulb would last about 5 seconds... if that.
Can you use 220 volt light bulb on 120 volt system - I know the reverse would probably blow the bulb so wouldn't European 220 Volt do ok in 120 volt socket or would it be dimmer than it normally would?
Yes a 220 volt light bulb will run on a 120 volt circuit but at 1/4 of the wattage that the light bulb is rated at. A 100 watt light bulb on 220 would would be equal to a 25 watt light bult on 120 volt system.
Can you replace a 110 volt 35 watt halogen bulb with a 120 volt 35 watt bulb?
Yes, you can replace a 110 volt 35 watt halogen bulb with a 120 volt 35 watt bulb, as the wattage is the same. The slight difference in voltage (110V vs. 120V) generally won't affect performance, as most bulbs can operate within a range of voltages. However, ensure the fixture is rated for the wattage to avoid overheating. Always check the specifications of your fixture for compatibility.
How many amps does a 120 volt AC 8 watt led bulb draw?
It is drawing .06 amps.
Can a car battery light up a 60 watt regular light bulb with out using a power inverter?
Yes it it is a 12 volt DC light bulb. It will not operate a household 120 volt light bulb.
How many amps to light a 60 watt light bulb?
A 60 watt light bulb typically draws 0.5 amps from a 120-volt power source. This is calculated by dividing the wattage (60 watts) by the voltage (120 volts).
What is the maximum power consumption of a 120 watt bulb?
The maximum power consumption of a 120 watt bulb is 120 watts.
Can you use a 145 volt bulb in a 120 volt lamp?
No, a light bulb rated to work in a 120 volt lamp will not work properly in a 12 or 24 volt low volt lighting fixture. I don't believe it will harm the fixture. If you did get a 120 volt light bulb to fit into a low voltage light it would probably just be dim.
