Look on the light bulb for the voltage and the power in watts. Then divide the watts by the voltage and that gives the amps.
Some CFL bulbs also state the current as well as the voltage and power, which is because they can have a poor power factor.

∙ 10y agoThere are zero amps in a light bulb. The amperage that a bulb draws is dependant upon the voltage that is applied to the bulb and the wattage rating of the bulb. The equation for amperage is Amps = Watts/ Volts. When you establish what these parameters are, using the equation will give you the answer that you are looking for.

How many watts does a 18 watt floresent light bulb consume?
Divide the wattage by the voltage. If it is 120Volt then the answer is .15Amp
How many amps will a 260 ohms resistor on a 120 volt circuit use?
Just use Ohm's Law Voltage = Current x Resistance Amps = Voltage Divided By Resistance Amps = 120 / 260
How does a bulb in a circuit light up?
A light bulb (called a lamp by the industry) will emit light when a voltage is applied to it. The applied voltage causes current flow through the lamp, and the lamp responds by emitting light. (There are many different lamps and they work differently, and we're generalizing here.) The lamp doesn't care whether the voltage that drive current through it comes from. It responds to the voltage (and current flow) according to its rating. If a given voltage is nominal for a lamp under inspection and we apply that, that lamp can be powered up by a generator, a battery, solar cells, or a number of other sources. Apply the appropriate voltage, and the lamp responds.
A 14 volt lightbulb is equal to how many watts?
If you have 14 watts, you have 14 watts of power. We measure electromotive force (EMF), which is commonly called voltage, in volts. EMF (voltage) is the force that will drive electron current flow, which is measured in amps. Simply put, power is current times voltage, or, said another way, watts is amps times volts. If you have 14 watts, you could have 14 amps at 1 volt, 7 amps at 2 volts, 2 amps at 7 volts, or any other combination of current and voltage with a product of 14. You may have picked up that because watts is amps times volts, we can say that a watt is a volt-amp. Extending that thinking, 14 watts is 14 volt-amps. There is no way to write 14 watts in volts, at least not without having a bit more information.
How many amps will a 120 kw dc motor require?
Depends on the voltage.
A 500 watt pool light pulls how many amps?
To answer this question the voltage of the bulb is needed.
How many amps does a led light draw?
Depends on the size of the LED light and the voltage applied. An example is an LED 24 volt globe light that pulls 8 watts which draw 0.333333 amps. Take an LED 120 volt light bulb draws 12 watts and will pull 0.1 amps. The same bulb at 240 volts wil draw 0.05 amps. it really depends on the watts and voltage applied. An average would be about 0.1 amps.
How many amps does a 50 watt bulb use?
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 many amps in a 50 watt 12v light?
Amps = Watts/Volts55/12= 4.583333
How many amps are needed to run a light bulb?
If you divide the watts of the bulb by the supply voltage, that is the current. For example a 60 w bulb on a 240 v supply gives a current of 60/240 which is ¼ amp.
How many ampere in 240 volt with 100 watts bulb?
Current (amps) = power (watts) / voltage = 100/240 = 0.42 amps
How many volts does a fluorescent light bulb need?
The correct voltage should be printed on the light bulb.
How many amps does a 34 watt flourescent bulb pull?
It depends on the voltage; which depends on the country. If you know the voltage, divide the wattage by the voltage, the result is the amperage.
How many amps does a 65 watt light bulb have at 120 volts?
The amps drawn by a 65 watt light bulb should be 65/120 or 0.54167. This fraction of an ampere may be restated as 541.67 milli-amps.
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 does a 120v 50w halogen light bulb use?
At what voltage? Until you tell me the voltage I can't give you an answer. To find out Amps you need to divide the Watts by the Volts. At 120V you have 0.4 amps. At 12V you have 4 amps.
How many amps does a two-bulb 32 watt 48-inch fluorescent light draw?
draw 0.104 amps
