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