How long would a 12 volt 7 amp hour battery last if converted to 120 volts ac using 20 watts?
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.

How many Watts in 200 Volt?
To determine Watts from Volts, you also need to know the current in Amperes (A) using the formula: Watts = Volts x Amperes. Therefore, 200 Volts alone cannot be converted into Watts without knowing the current. For example, if the current is 10 Amperes, then the power would be 200 Volts x 10 Amperes = 2000 Watts.
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 in a 18650 3.7 volt battery?
The wattage of a 18650 battery can be calculated using the formula: Watts = Volts × Amperes (Ah). A standard 18650 battery has a nominal voltage of 3.7 volts, and its capacity typically ranges from 1800mAh to 3500mAh. For example, a 3000mAh (or 3Ah) battery would provide approximately 11.1 watts (3.7V × 3Ah = 11.1W). Therefore, the wattage varies depending on the specific capacity of the battery.
How many watts to vaults?
Watts (W) and volts (V) measure different electrical properties, so they cannot be directly converted without additional information. Watts measure power, while volts measure electrical potential. To relate them, you need to know the current in amperes (A) using the formula: Watts = Volts × Amperes (W = V × A). Thus, the conversion depends on the current flowing through the circuit.
How many watts does my 12 volt 2 amp battery charger draw?
Volts * Amps = Watts 12 Volt * 2 amp = 24 Watts
How many Watts in 200 Volt?
To determine Watts from Volts, you also need to know the current in Amperes (A) using the formula: Watts = Volts x Amperes. Therefore, 200 Volts alone cannot be converted into Watts without knowing the current. For example, if the current is 10 Amperes, then the power would be 200 Volts x 10 Amperes = 2000 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 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 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 450 watts?
