Using the equation Volts X Amps = Watts, you can take 3000 watts / Volts to get your answer:
3000W/240V = 12.5A
or
3000W/120V = 25A
So, at 240 volts you will use 12.5 amps for 3000 watts of power. Or at 120 volts you will use 25 watts.

To calculate the amperage, divide the watts by the voltage. For example, at 120 volts, 3000 watts would pull 25 amps (3000 watts / 120 volts = 25 amps).
Depends on the voltage. In general, Watts = Voltage x Amps. So Amps = Watts / Voltage.
Example: 30,000 Watts / 120 Volts = 250 Amps.
There are zero amps in 3000 watts. One equation for amps is I = W/E.
Where I = amps, W = watts and E = volts.
To calculate the amperage, you need to use the formula: Amps = Watts / Volts. Assuming a standard voltage of 120V, you can calculate the amperage by dividing 600 watts by 120 volts, which equals 5 amps. Therefore, 600 watts would require 5 amps of current at 120 volts.
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.
Power(Watts) = I (Amps) x E(Voltage) PIE rule. so 1000 = I x 240. 1000/240 = 4.16667 amps.
A typical 120 volt diesel engine block heater can pull around 1000-1500 watts, which would translate to approximately 8-12.5 amps. It's important to check the specifications of the specific block heater you are using to get an accurate measurement.
A 1500 Watt heating element about 1500/110 or 13.64 Amperes from a 110V service. It is assumed the heating element is made from a resistive wire.
