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.

∙ 8y agoA 100W 12V DC bulb would draw approximately 8.33 amps. This is calculated by dividing the power (100W) by the voltage (12V).

∙ 13y ago8.33 A
P=IV
therefore I=P/V
I=100/12
I=8.33A

∙ 13y agoThe formula you are looking for is I = W/E , Amps = Watts/ Volts.
1000 / 12 = 83.33 A

∙ 10y agoDivide the watts by the volts, so it's 130 divided by 12, and the answer is in amps.
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.

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.
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.

amps equals watts divided by volts.

It is drawing .06 amps.
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).

A 100W incandescent light bulb typically produces around 1600 lumens of light.
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.

Watts = Volts x Amps x Power Factor. An incandescent light bulb is a resistive load so PF = 1. ANSWER: = 1/2 Amp
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.
A 120 volt table lamp with a 75 watt bulb will pull 0.625 amps. With a 100 watt bulb it will pull 0.833 amps. And with a modern fluorescent 13 watt bulb it will pull 0.108 amps.

To calculate the amperage drawn by the heater, you can use the formula: Amperage (A) = Power (W) / (Voltage (V) * Square root of 3). In this case, the amperage drawn will be approximately 5.8 Amps.
