Look on the devices nameplate. There it should have the wattage, volts, and amperage.
To calculate the amperage, use the formula: Amps = Watts / Volts. In this case, it would be 580 watts / 120 volts = 4.83 amps. Therefore, you would need approximately 4.83 amps for a 580 watt device at 120 volts.
To calculate the wattage of a device using 10 amps, you would need to know the voltage it operates on. The formula is Watts = Amps x Volts. So, for example, at 120 volts, 10 amps would be equal to 1200 watts.
A very basic formula is that power (watts) equals amperage times voltage. For example, if you are operating at 120 volts, 580 watts, the amperage would be 4.8 amps (580 divided by 120).
Volts * Amps = Watts 12V * A = 150W A = 150W/12V A = 12.5
To calculate the number of amps, you need to know the voltage of the circuit. Using the formula Amps = Watts / Volts, if the voltage is 120V, then 9.8kW at 120V would be approximately 81.67 amps.
To calculate the amperage, use the formula: Amps = Watts / Volts. In this case, it would be 580 watts / 120 volts = 4.83 amps. Therefore, you would need approximately 4.83 amps for a 580 watt device at 120 volts.
An electrical device may draw amps, but there is not a device that equates to amps. Amperes are the measure of current flow in a circuit.
To work this out you will need to know the current that is travelling through the device. You can then find the number of volts by dividing the power (watts) by the current (amps).
To calculate the wattage of a device using 10 amps, you would need to know the voltage it operates on. The formula is Watts = Amps x Volts. So, for example, at 120 volts, 10 amps would be equal to 1200 watts.
The electrical device supports an amp range of 0 to 10 amps.

To charge a car battery you need aproximatly 8000 amps To charge a car battery you need aproximatly 8000 amps
There is no formula it depends on the device. If the device is linear it can be ascertain but if it a non linear then it becomes quite complex
A very basic formula is that power (watts) equals amperage times voltage. For example, if you are operating at 120 volts, 580 watts, the amperage would be 4.8 amps (580 divided by 120).
The maximum current rating for the circuit breaker needed for a device that operates at 20 amps is 25 amps.
You need amps
UPS batteries are typically rated at how many ampere hrs they can supply. IF your 20 Watt device is supplied by 120V then it draws 1/6 amps. (Watts = Amps * Volts for a resistive load). If your UPS were rated for 1 A Hr you could power your device for 6 hours.
