It doesn't really work that way.
For each battery there's a given maximum current that the battery can deliver, and for each load(=thing powered by the battery) there's a given current that the load can pull.
So to get to 1000 watts you need a load that can use 1000 watts, and a battery that can deliver that current
You get amps by taking watts / volts, so 1000/12 = 83 amps
So a load capable of pulling 83A and a battery capable of delivering 83A will basically give you your 1000W.
Now, one basic car battery will be able to deliver 83A/1000W, even more, but only for a short period of time. Not only will it drain the battery rather quickly, but at that power, you're also looking at possible overheating and other nasties.
Several batteries in parallel would be a better option, but not that easy to set up well.
What else can I help you with?
How many watts does 20 amps at 240 volts produce?
The unit of power is expressed in watts, and the product of current (Amps) and voltage (volts) is power there fore if you multiply the amps and the volts give watts. so 20 x 240 will give you a 4800 watts of power.
What does it cost to run a 5.8 amp motor at 120 volts?
Use the following formula to find the watts used. W = Amps x Volts. Divide that number by 1000. This will give you kWs. Determine how long the motor is to run and multiply this amount by the kilowatts you calculated. This will give you kW/hours. On your utility bill it will be stated how much you pay for a kW/h. Multiply that by your answer and you can estimate how much it costs you to operate the motor.
2.1 amps x 12 volts equal how many watts?
.183A or 183 Milliamps. Power/Watts Divided by Voltage will give you Amperes
400 volts x 45 amps?
Multiplying 400 volts by 45 amps would give you a power output of 18000 watts, which is equivalent to 18 kilowatts (kW).
How many watts in amp at 220 volts?
That of course depends on who made the water heater and what model number it is you could always call the manufacturer. Quickest way I know of is to look at the heating elements. They will have a wattage rating. This number is visible when you take the cover or covers off, move aside the insulation and use a flashlite to spy the pesky little rascals.I suggest you shut off the voltage first. My 80 gal has 2 elements of 4500 watts each if I'm not mistaken. All you need to do is multiply the Volts by the Amps and that equals watts
1kw how many amps?
1 kW = 1000 watts. Formula is Watts = Amps x Volts. As you can see to give you a answer I need a value for volts. Transpose the formula to read I = 1000/volts.
How many amps do 8 6 volt dc batteries put out?
The amperage drawn from batteries is governed by the connected load. The voltage of the batteries can be one of two voltages. in parallel the 8 batteries will give you a voltage of 6 volts. In series the 8 batteries will give you a voltage of 48 volts. The amp/hour capacity of the batteries will give you the amount of current the device can draw over a specific length of time. Equation to fine amperage is I = W/E, Amps = Watts/Volts. Watts = Amps x Volts.
How many amps will give you a kW?
Amps can not give you a kilowatt with out a voltage being applied to the question. Watts = Amps x Volts. Amps = 1000/ Volts.
What has more power 4 batteries of 1.5 volts each or a single battlery of 4.8 volts?
If you connect the four batteries in series, you get 1.5 x 4 = 6 volts total. So the four batteries give more volts.If the question is which alternative will deliver more power as in watts, that depends on both the batteries and the application. As an example, a 12 V car battery has higher capacity and can deliver far more watts than eight torch batteries in series for the same number of volts.But as long as the maximum current the application draws is no higher than what the smallest batteries can deliver, the power (watts) will depend only on voltage.
Amps to watts conversion?
Get the volts and multiply that by the amps. This will give you the watts.
How many watts is 18.5 volts?
Watts is the product of amps x volts. To give an answer the amperage needs to be given.
How many watts does 20 amps at 240 volts produce?
The unit of power is expressed in watts, and the product of current (Amps) and voltage (volts) is power there fore if you multiply the amps and the volts give watts. so 20 x 240 will give you a 4800 watts of power.
How do I figure watts if I know voltage and ohms?
Volts time amps equals watts so watts divided by volts equal amps.
Can you parallel 4 sets of 6 volt batteries to get 12volts at the same time having the same batteries in series for a 48 volt laod?
Paralleling four sets of 6 volt batteries will still give you 6 volts. Two 6 volt batteries in series will give you 12 volts. Parallel these series sets will give you longer endurance at 12 volts. There is no way you will ever get 48 volts out of four 6 volt batteries.
How do you get 24 volts from 2 batteries not in series?
Two 24 volt batteries in parallel will give you 24 volts. The only other way is two 12 volt batteries in series.
What does it cost to run a 5.8 amp motor at 120 volts?
Use the following formula to find the watts used. W = Amps x Volts. Divide that number by 1000. This will give you kWs. Determine how long the motor is to run and multiply this amount by the kilowatts you calculated. This will give you kW/hours. On your utility bill it will be stated how much you pay for a kW/h. Multiply that by your answer and you can estimate how much it costs you to operate the motor.
How many amps does one kilowatt make 240 volts single phase?
There is one part of the question missing. To find an answer the kW of the heater must be stated. Then the equations used are, to change kW to watts, Kw/1000 = watts. Once that is found then use, I = W/E, Amps = Watts/Volts. This will give you the value in amperage of the heater.
