What gauge wire do you need for 12 volts at 4.2 amps in my car for a light H11 Light bulb?

Almost any size wire will handle the 4.2 amps. BUT...as with any wiring, you must look at the over current device to determine the proper size. You need to determine which fuse in the fuse panel protects that circuit and use a wire that is appropriate for that size fuse.

Why Battery light on and gauge says charging?
your gauge only measures volts. not amps. when alternators get tired sometimes they wont produce enough amps to run the car. your computer might see this where the gauge still says 12-14 volts. basicly your running off the battery. if that doesnt work then check battery for poor cell. last call put tape over the light,lol. good luck
How many amps are required for 100W light bulb operate on 110 volts?
amps equals watts divided by volts.
What kind of amps does a 65 watt light take?
amps equals watts divided by volts.
What is the resistance of a 40 watt bulb?
On this calculation I am assuming that the light bulb is using a 120 volt source. Watts = Amps x Volts. Amps = Watts/Volts, 40/120 = .33 amps. R = Volts/Amps, 120/.33 = 363.6 ohms resistance in the 40 watt light bulb.
If you have a power supply that puts out 4.5 volts and 2 amps but the light you have only needs 4.5 volts and 1 amp will you fry the light?
It's highly possible. The difference in amperage might be minuscule but it all depends on the gauge of the wiring, the resistors, and the capacity of the board.
What is the max amps for 14 gauge wire at 12 volts?
15 amps
How many amps does a 65 watt light bulb use?
Amps x volts = watts So, assuming you are running on 110 volt line, the answer is 65 watts/110 volts=.591 amps.
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 do 12v 25w light use?
well the equation for amps is a= watts/volts so 25/12= 2.0833333333amps
What is ampere rating of 10 gauge wire at 120 volts and at 240 volts?
30 amps.
What is the curren in an ac circuit with 120 volts and a 60 watt light bulb?
You want to know how many amps in that circuit. To do so, divide the Watts by the Volts. in your case it would be 60 watts / 120 volts = 0.5 Amps.
How many amps does 300 watt floodlight draw?
If the light is operating at 110 volts, and P = I x E, then I = 300/110, or 2.5 amps.
