The basic formula for the Voltage, Current, Power relationship is P=I*E.
To find one when the other two are known, simply fill in the two you know and solve. In this case P=1000W and Voltage = 240V (It is important that you pay attention to the unit definer here, if it were 240 mV, you would have Voltage = .240V and so on).
1000W = I * 240V
I = 1000W/240V
I = 4.17A

How do you use Japanese light bulb 100V in Malaysia which is 240V?
get a step down transformer whose output is equal to the voltage of your bulb
A 500 watt pool light pulls how many amps?
To answer this question the voltage of the bulb is needed.
What does amps do in a light bulb?
Take the wattage of the bulb and divide that by the voltage of the bulb. This will give the current the bulb draws. Amps are a measure of charge (electron) at an instant of time through a conductor. In an incandescent bulb the filament is heated by the current and the characteristics of the filament, usually tungsten, is that it gives off light when heated.
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 in a 50 watt 12v light?
Amps = Watts/Volts55/12= 4.583333
How many amps in a low voltage light bulb?
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.
Can the resistance of a light bulb permanently change after it had been used for years?

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.

Could a light at 110 voltage be used in UK?
The light bulb will probably burn out, if the fuse of the lamp does not burn out first. On the other hand, a lamp with 240V rating can still be used in the USA, but the light will be about half as bright for the same light bulb.
What is the amps from a small light bulb?
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.
Why does a light bulb light in a closed circuit?
A bulb does not light up if there is no voltage available across the bulb, or if the bulb is burned out.
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 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.
