Two.
More Information:Refer to the electrical formula:Amps * Volts = Watts
The above answer is correct for HOUSEHOLD bulbs in the U.S. or Canada where we use 120V.
A * 120V = (60 * 4)
A = (60*4)/120
A = 240/120
A = 2
But of course, the answer would be different if the bulb voltage were different.

How many watts are consumed by a light bulb if 1.2 amperes are measured when 12 volts are applied?
The power consumed by the light bulb can be calculated using the formula P = I * V, where P is power in watts, I is current in amperes, and V is voltage in volts. In this case, the power consumed is 1.2 amperes * 12 volts = 14.4 watts.
How many watts did CFL uses?
Depends on the light. Typically about 1/8th of the wattage used by an equivalent standard bulb.

How many killawatts are in a standard light bulb?
"A standard light bulb I would consider to be a 60 watt light bulb, and kilowatts are the amount of usage in a light bulb. From my research I have found that a standard 60 watt light bulb uses approximately 1.44 Kilowatts per hour."
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 kilowatts does a light bulb use?
Thsi depends on the light bulb specification. For example if you buy a standard 60W light bulb from your supmarket then this will consume 0.06kilowatts. Its simple just divide the wattage stated on the light bulb by 1000 to give you the kilowatts
How many watts are consumed by a light bulb if 1.2 amperes are measured when 12 volts are applied?

How many 1.5 volt batteries does take to light up a big light bulb?
Is the bulb a 1.5 volt bulb? A 3 volt bulb? A 12 volt bulb or a 120 volt bulb?Or does it have some other voltage such as 230 volts which is very common in Europe and many other countries of the world?What is the wattage of the "big light bulb"?This question cannot be answered without knowing at least the voltage and the wattage of the light bulb that is being asked about.
What kind of light bulb does a easy bake need?
You would have to check the manual. It may even be embossed on it. The light bulb is usually a standard 100watt. But because there are so many models it may require more or less wattage.
