How long will a battery 12 ampere-hour rating supply 144 watt load?

An ampere-hour rating is a relatavistic indication of how long a battery can supply a specific current.It is not possible to determine the run time when you only gave watts, but watts are volts times amps, and you did not supply the volts.


How many kilowatts does it take to run 100 amp home?

A three wire home distribution service rated at 100 amps has a wattage capacity of;From L1 to L2 at 240 volts x 100 amps = 24000 watts or 24 kilowatts. From L1 to neutral at 120 volts x 100 amps = 12000 watts or 12 kilowatts. From L2 to neutral at 120 volts x 100 amps = 12000 watts or 12 kilowatts.


What is most important in dc power -volts-watts or amps?

You didn't define "importance" so it is hard to tell. They are all related by the formula Watts = Volts x Power Factor. Power Factor varies from zero to one. One thing that is often done in an application is to try to reduce the current and proportionally increase the voltage to obtain the needed wattage. That is why most electric stoves run at 240 volts rather than 120 volts, because 1/2 the current is required at the higher voltage; and you can use smaller wire and connect to a lower amperage breaker.

How many kwh are used by a 12 volt battery?

Every battery has a rated life in kilowatt hours or ampere hours. There is no way of knowing what battery you are referring to. To supply one 1000 watts (1 kilowatt) of energy at 12 volts, the battery must supply 83.33 Amps at 12 Volts. If battery supplied 83.33 Amps for one hour then 1 KWh would be the result.

What can you run on ten amps?

At 120 volts you can operate any equipment up to 1200 watts. At 240 volts you can operate any equipment up to 2400 watts.


How many lines can you run off 110 volts of electricity?

As many as will fit. The limit is usually determined by other factors, such as how many amps or watts are required rather than how many volts.

How many 78 Amp fans can you run on 30 watts?

Assuming you mean 12 volts, then you cannot run any 78 Amp fans. Unless your fans run at 0.38 volts, there is no way to draw 78 amps from 30 watts.


How many watts is to run 12 volt drill charger?

To determine the watts needed to run a 12-volt drill charger, you can use the formula: Watts = Volts x Amps. If you know the amperage of the charger, you can multiply it by 12 volts to find the wattage required.


What can you run off an 8000 watt generator?

Watts = Amps x Volts. Amps = Watts/Volts. 10000/120 = 83.3 amps can be used at 120 volts. On a generator that large it is most likely that it also has the capacity to produce 240 volts. 10000/240 = 41.6 amps can be used at 240 volts. What you can connect to the generator will be totals of the amperage of devices that do not go above these amp ratings.


How many watts will it take to run a 120 volt 1 hp motor?

A 1 HP motor running at 120 volts will draw approximately 746 watts. This calculation is based on the formula: Watts = Volts x Amps.


How many watts can run through 12-3 wire?

Wire is rated in ampacity, You can use only 80% of the rated ampacity. Voltage and amperage are inversely proportional. So at 120 volts alternating current you safely run 1800 watts ( I have added a small safety margin). At 240 volts you can run 3600 watts. I hope this has answered you question Ampsxvolts=watts watts/volts=amps


Can you run appliances off 220 volts?

Yes, if the appliance was designed to run on 210 to 240 volts.


How many watts can a 250 volt circuit run at 30 amps?

The formula you are looking for is W = I x E, Watts = Amps x Volts.


How many amps is needed to run 3200 watts?

Watts = Amps x Volts x Power Factor For a motor the Power Factor is less than 1 and might typically be about .75. For a resistive load like a toaster PF = 1. If you know the Voltage and PF and know the wattage you can calculate amps. Amps = Watts / (Volts x PF)


How many volts in 90 watts?

Wrong question. I assume that this pertains to a car and not a house. All modern cars run on a 12-volt system. So what I think you meant to ask is "how many AMPS in 90 watts at 12 volts?". Watts divided by volts equals amps, so 90 watts divided by 12 volts equals 7.5 amps. If you are trying to wire in a car stereo amp, better go with a 10 amp fuse.
