A lamp doesn't care whether it operates from a 12-V d.c. supply or from a 120V a.c. supply -all that matters is the supply must be 12 V!

If it's connected to a 12-V d.c. supply, then it will draw a current of 8.33 A; if it's connected to a 12-V a.c. supply, it will still draw a current of 8.33 A.

A 100W 12V DC bulb would draw approximately 8.33 amps. This is calculated by dividing the power (100W) by the voltage (12V).

8.33 A

P=IV

therefore I=P/V

I=100/12

I=8.33A

The formula you are looking for is I = W/E , Amps = Watts/ Volts.

1000 / 12 = 83.33 A

Divide the watts by the volts, so it's 130 divided by 12, and the answer is in amps.

amps equals watts divided by volts.


How many amps does a two-bulb 32 watt 48-inch fluorescent light draw?

Each 32-watt bulb in a 48-inch fluorescent light typically draws around 0.27 amps. Therefore, a two-bulb setup would draw approximately 0.54 amps in total.

It is drawing .06 amps.


How many amps does a 5 watt 12 volt bulb draw?

To calculate the amperage, you can use Ohm's Law formula: Amperage (A) = Power (W) / Voltage (V). In this case, for a 5 watt bulb at 12 volts, the amperage drawn would be 0.42 amps (5W / 12V = 0.42A).

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.


How many amps will a 60 watt bulb draw from 120 volts?

Watts = Volts x Amps x Power Factor. An incandescent light bulb is a resistive load so PF = 1. ANSWER: = 1/2 Amp


How many amps does 65 watt light bulb draw?

A 65-watt light bulb operating at 120 volts draws approximately 0.54 amps of current. You can calculate this by dividing the wattage (65 watts) by the voltage (120 volts) to get the amperage.
