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.
To power an incadescent light bulb you need anywhere between 1.5 volts and 300 volts.
amps equals watts divided by volts.
4.34 @230v
amps equals watts divided by volts.
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.
Yes, even a potato can light a light bulb. Yes. If the batteries match the voltage of the bulb, they can light it. Flashlights have bulbs and batteries that power them. If you mean a household light bulb, then you'd need many batteries in series (80 of the 1.5 volt batteries).

To answer this question the voltage of the bulb is needed.
Watts = Volts x Amps for an incandescant bulb. So Amps = 600/120.
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.
Amps = Watts/Volts55/12= 4.583333
draw 0.104 amps
A 65 Watt incandescent light bulb should draw 65W/120V = 541.67mA
amps equals watts divided by volts.
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.
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.
240v is equal to how many amps
Depends on your light usually it's a 60 wat balb
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.
