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

Why are some appliances rated in watts and others amps?

Appliances are rated in watts to indicate the total power they consume, which is the product of the voltage and current they draw (P = V x I). Some appliances may also be rated in amps, which measures the current they require from the power source. Both ratings are important for determining electrical loads and ensuring safety.


How much watts are in a 7v battery?

Electric power = Volts X Amps, so 7 vols at 1 Amp will produce 7 watts 7 volts at 5 amps will produce 35 watts 7 volts at 15 amps will produce 105 watts and so on. Technically, there is not enough information (just volts) to answer your question but if you know the Amps, you can now figure the answer yourself.


You were given aload 2500 watts how much it draw amps?

To calculate the amperage draw, you need to know the voltage of the circuit where the 2500 watts appliance will be used. You can use the formula: Amps = Watts / Volts. For example, if it is a 120V circuit, the amperage draw would be 2500 watts / 120 volts = 20.83 amps.


How much watts are in calculators?

Watts = Amps x volts. What is the current draw and voltage of the calculator.


How many watts are in 19.5 volts?

Impossible to know. You need to know both the voltage and current draw to calculate power (watts). Power in watts = Volts X Amps


5000 watts at 240 volt will draw how many amps?

To find amps if watts and volts are known, use the formula; watts / volts = amps or 5000 / 240 = 20.83 amps


How many watts does a 16 amp appliance draw at 115 volts?

1840


How do you figure the watts of a 110 volt pump that is 135 hp and has an amp draw of 54?

Yes, power = voltage x current = 54 x 110 = 5940 watts. But the odd thing is the rated horsepower. I was taught that one horsepower = 746 watts, so 135 hp = 100,000 watts. Are you certain that the pump is rated at 136 horsepower? Or can anyone else address the discrepency? W=volts X amps; therefore W= (110)(54)


How many amps in 70 watts?

To answer this you have to know how many volts will be used. If you know the voltage then you can calculate the current by dividing voltage into wattage. For example; an electric heater rated at 700 watts when plugged into a 115 v outlet will draw 700/115 = 6.08 amps of current.


How many amperes use an electric heater?

The amperage of an electric heater depends on its power rating in watts and the voltage it operates on. To determine the amperage, divide the wattage by the voltage (Amperes = Watts / Volts). For example, a 1500 watt electric heater running on 120 volts would use 12.5 amperes (1500 watts / 120 volts = 12.5 A).


15000 BTU RV Conditioning is how many Watts?

approximately 1440 watts. Or a 12 amp draw @120 volts ac. Older units will draw more current. This is the draw after start up.


2400w equals how many amps in 12v?

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