Assuming this could be done with no conversion loss a 20 watt load at 120 volts would require about 1/6 of an amp. A 7 ampere hour battery would run the load for 6 x 7 = 42 hours.

However, if you actually built a circuit to up convert 12 volts DC to 120 volts AC there would be significant conversion losses.

What is the watts if a 12 volt battery produces 2.7 amps?

The power output of a 12-volt battery producing 2.7 amps can be calculated using the formula: Power (watts) = Voltage (volts) x Current (amps). So, in this case, the power output would be 12 volts x 2.7 amps = 32.4 watts.


How many watts does my 12 volt 2 amp battery charger draw?

Volts * Amps = Watts 12 Volt * 2 amp = 24 Watts


How many watt in amp?

It's watts divided by volts equals amps. Example: 1200 watts at 120 volts is 10 amps. To get the watts if you know the amps, multiply the amps times the volts. 10 amps at 120 volts is 1200 watts.


Why kilo watts converted in kilo volts?

Kilowatts are never converted to kilovolts. There's no direct relationship between them, without involving other quantities in the circuit. Watts = (volts) times (amperes) Kilowatts = (kilovolts) times (amperes) Kilovolts = kilowatts/amperes


How many amps are in 2000 watts using 110 volts?

To calculate the amps, you can use the formula: Amps = Watts / Volts. So, for 2000 watts and 110 volts, 2000 watts / 110 volts equals approximately 18.18 amps.


How do you solve for current using volts and watts in a problem?

Amperes measure the rate of flow of electricity in a conductor Volts measure electrical pressure Watts measure the amount of energy or work that can be done by Amperes and Volts Relationship: Work = Pressure x Flow or Watts = Volts x Amperes When you know two variables you can calculate the other Formulas - This formula referred to as the West Virginia Formula (W - VA)Watts = Volts x Amps Volts = Watts / Amps Amps - Watts / Volts Refer to link below for more information


How do you find OHM?

Ohms can be found by using these formulas. Ohms = Volts/Amps, Ohms = (Volts (squared))/Watts, Ohms = Watts/(Amps (squared)).


How many amps is 500 watts for a jump starter?

To calculate the amps for a jump starter with 500 watts, you can use the formula: Amps = Watts / Volts. If assuming a standard 12-volt car battery, the calculation would be 500 watts / 12 volts = 41.67 amps.


How many amps is 450 watts?

450 watts divided by 120 volts equals 3.75 amps450 watts divided by 12 volts equals 37.5 ampswatts divided by volts equals amps


What does 1.5 watts equal to amp using 12 volts?

volts times amps equal watts. So 12 volts times ? amp equals 1.5 watts. The current is 1.5/12 amps, which is 1/8 amp.


Is 17 watts 120 volts?

No. Watts = Volts x Amps Watts does not directly convert to volts.


37.5 amps converted in watts?

To convert amps to watts, you also need the voltage. The formula to calculate power in watts is Watts = Amps x Volts. If the voltage is 120V, then 37.5A would be equivalent to 4500W (37.5A x 120V = 4500W).
