Which 12 volt bulb will draw the most current when connected to a 12 volt battery?

The bulb with the lowest resistance. Current = Volts / Resistance

Can you use a 120 volt halogen bulb in place of a 110 volt halogen bulb?

Yes, the two voltages are in the same range category.


How do you know whether to get 120 volt or 130 volt light bulb?

Choose a bulb with the same voltage as your fixture to prevent damage or risk of overheating. If the fixture specifies 120 volts, use a 120-volt bulb. If in doubt, consult the manufacturer's instructions or a professional electrician.


What happens if you use a 120 Volt bulb where a 130 volt socket?

Using a 120 volt bulb in a 130 volt socket may cause the bulb to burn out more quickly or not function properly. The higher voltage from the socket can lead to a higher current flowing through the bulb, which can damage it or cause it to fail prematurely. It is always best to match the voltage of the bulb with the voltage of the socket for optimal performance and safety.


Can a 230 volt bulb be used on a 120 volt circuit How does this impact wattage of the bulb?

Yes, a 230V bulb can be used on a 120V circuit, but the power output of the bulb will be approximately one quarter. (Half the voltage and half the current) Note, however, that since the bulb will be cooler, the resistance will be slightly less, so power will be somewhat higher than expected, but estimated figure is still one quarter.


Will a 12 volt auto light-bulb work on 12 volt AC?

Yes, a 12 volt auto light bulb can work on 12 volt AC, but the light output might be slightly lower compared to when using DC. The bulb will still produce light, but it may flicker due to the alternating current.


How many amps does a 120 volt AC 8 watt led bulb draw?

It is drawing .06 amps.


What gives the biggest resistance 3 volt bulb or 6 volt bulb?

3 volt bulb gives the biggest resistance


Does amperage and a voltage mean the same thing?

No. Amperage is the current flowing down the conductor as voltage is a constant (relatively). As an example- a 120 volt light bulb is of course 120 volts but if it is 60 watts then it will draw .5 amps. a 100 watt bulb will draw around .8 ampsDifferent things.


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.
