You just have to divide the watts by the voltage to find the amps. For example 60 watts on a 120 v system would take ½ amp.

How much energy does a nightlight use compared to a 100 watt bulb?
An incandescent nightlight bulb is either 4 watt or 7 watt. A 4 watt bulb uses 1/25th (0.04) the power of a 100 watt bulb. A 7 watt bulb uses 7/100th (0.07) the power of a 100 watt bulb. There are LED and other types of nightlights that use much less power than this. To find the energy total used multiply the power (in watts) by the total time the light is on (in hours) to get energy (in Wh). If you want kWh divide this by 1000 as a watt is 1/1000th of a kW.
How many amps do light bulbs draw?
Depend on watt and voltage use of light bulbs. You can use this ohm's law formular to calculate the current draw on light bulbs. I (current in amp) = P (watt)/ E (voltage) If 25W light bulb use in 115V AC (resident home) then current draw will be: 25/115 = 0.22A or 22 miliamperes. Hope this help.
Can you use a 36 watt fuse for a 40 watt fluorescent bulb?
Fuses are not rated in wattage, they are rated in amperage and voltage.
Can you use a 100 watt HPS bulb in a 70 watt hps fixture?
In general no, because the extra heat produced would make it a fire hazard.
What is a lumen How does it relate to watts?
A lumen is a unit of luminous flux, which is the amount of light emitted per unit time. A watt is a unit of power (such as electrical power), which is the amount of energy consumed per unit time. Light bulbs have ratings in watts, which measures how much electricity they use, and lumens, which measures how much light they give off. For the same kind of bulb (incandescent, fluorescent, LED, etc.), a bulb with a higher wattage will produce more lumens. However, a 10-watt LED or compact fluorescent bulb may produce more lumens than a 40-watt incandescent bulb.
How many amperes does a standard 60 watt light bulb use?
Watts = Volts X Amps. Amps=Watt / Volts. So, with a 240V mains, a 60W bulb draws 0.25amps. On a 12 system (car/auto) a 60W bulb draws 5 amps. On a 110V mains, a 60W bulb draws .55 Amps.
How many amps in a 300watt bulb?
There are zero amps in a 300 watt bulb. Watts are the product of amps times volts. W = A x V. To find amperage use the equation A = W/V. If you find the voltage of the 300 watt bulb uses, divide the wattage by the voltage and it will give you the amps of a 300 watt bulb.
How many amps does a 65 watt light bulb use?
Amps x volts = watts So, assuming you are running on 110 volt line, the answer is 65 watts/110 volts=.591 amps.
How many amp hours does a 23 watt bulb use?
The formula for finding amperage is I = W/E. Amps = Watts/Volts. Without the value of the voltage to the bulb this question can not be answered.
How many amp hours does a 13 watt bulb use?
A 13W bulb consumes 13W/110V=0.118 A.If you use it for an hour, it consumes 0.118 Ah, for 2 hours 0.236 Ah, and so on..AnswerLamps don't use ampere hours, as this is simply a unit of measurement for electric charge. You probably mean 'watt hours' which is a measure of energy. A 13-W lamp will use 13 Wh for each hour it is used.
How many amps does a 60 watt fridge use?
0.27 a
How much energy every second would a 100 watt light bulb use?
100 Joules = 100 watt second = energy1 joule = 1 watt second
How much wattage will the ballast and a 150 watt hps bulb use?
About 1.66 amps at 120 volts Ballasts have stickers on them that tell you the exact amps per the voltage that you are running
How many amps does a 175 watt mercury vapor light use?
depending on voltage supplying the bulb, each ballast spicifies on it such rating. many ballasts have better efficiency at higher voltage. however; say 175 watt bulb, 120V with 80% efficiency= (175/120)/.8=1.82amps
How many amps is needed to run a 1450 watt coffee maker?
A 1450 watt coffee maker will use around 13 amps at 110 volts.
How many kWh will a 32 watt fluorescent bulb use?
A 32 watt bulb uses 32 watt-hours, or 0.032 kWh, every hour it is used.
How many amps does a 1000 watt 120v ballast use?
Max amps would be 1000 divided by 120.
