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.
How many watts in 20 volts?
You need to have the amperage to determine how many volts you get out of 20 watts.
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 watts does a 16 amp appliance draw at 115 volts?
1840
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 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
How many watts in 20 volts?
You need to have the amperage to determine how many volts you get out of 20 watts.
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)

To find amps if watts and volts are known, use the formula; watts / volts = amps or 5000 / 240 = 20.83 amps
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.
How many watts does my 12 volt 2 amp battery charger draw?
Volts * Amps = Watts 12 Volt * 2 amp = 24 Watts
What is the kilowatt power draw of an electric furnace that measures 20 amps and 240 volts at it's power circuit?
For the furnace Watts = Amps x Volts Divide watts by 1000 to get 4.8KW.
What is the kilowatt output of an electric heater that has an ampere draw of 50 a and a voltage source of 208 volts?
The watts is the volts times the amps So 208 x 50 watts, or 10.4 kW.
