An ampere-hour is one ampere for one hour.
A ampere is one coulomb per second, so an ampere-hour is a transfer of charge of 3600 coulombs.

∙ 14y agoVolts = Amps x Resistance so Amps = Volts / Resistance
If you know Watts you can also compute Amps because Watts = Volts x Amps x PowerFactor.
In many cases you can set PowerFactor to 1 if motors are not involved. As an example if you have two 120 Watt Light Bulbs turned on and you have 120 V AC service (Typical) then the amperage being consumed would be 1 Amp.

∙ 11y agoTotal battery amp hours of the battery, divided by the amp draw, equals the life of the battery.
Example=
200 amp hours, divided by 5 amps, equals 40.00 hours.
There are many different factors. This is based on constant draw.

How much are 5400 Milli ampere hour in ampere hour?
There is a thousand milliamps in an amp. So it would be 5.4AH.
What do you mean by 800 Volt Ampere Hour?
ampere hour is the unit of electricity consumed by electrical load,for example you are consuming 5ampere per hour so unit of power will 5amp-hour,generally unit of power is kilowatthour,so 1000amp-hour =1KWH ampere =voltage/resistance, amp-hour the unit of power on which tariff is calculated for the consumption of electricity
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.
What will be battery charger ampere hour rating for 70 MW power plant?
Rephrase your question; as it stands, it makes no sense.
Who was ampere named after?
The ampere was named after André-Marie Ampère.
What is the electrical abbreviation mAh?
milliamphere Hour or one-thousandth of an ampere-hour
What is an Ampere hour?
An ampere hour (A.h) is a non-SI unit of measurement for electrical charge (the SI unit is a coulomb-which is equivalent to an 'ampere second'). So an ampere hour is equivalent to 3600 coulombs.Cells and batteries are generally rated in terms of ampere hours, as a convenient alternative to the kilocoulomb.

How much are 5400 milli ampere hour to make in ampere hour?
There is a thousand milliamps in an amp. So it would be 5.4AH.
How many amperes a 1.5 ton ac consumes in 1 hour?
I am not sure what you mean, but ampere is a unit of current, not of energy. In the case of a constant current, if the current is 1 ampere in a second, it will be 1 ampere in an hour, or in a day.
Where did Andre Marie Ampere do most of his work?
Andre Marie Ampere do most of his work in his dad's house.
How do you compute ampere-hour?
by multiplying by resistance and dividing by voltage
How much charging ampere required for 200 apmere lead acid battery for ups 12 volt?
To find our what charging ampere to use a simple way is to divide the battery Ampere with its ampere hour (i.e. for car batteries they will say 75ah C/20) this means that the battery has 75 ampere rating based on 20 hour rating... as such to find the charging ampere divide 75 by 20 to get a charging ampere of 3.75... this is for a slow charge - to speed up the charge divide the ampere by 5 hours (to charge the battery from empty to full in 5 hours)...
How do you get ampere hour from watt hour?
Watt = ampere x volt. So if you know the voltage, you can convert amperes to watts or vice versa. If not, you don't have enough information.AnswerThe ampere hour (A.h) is a unit of measurement for electric charge (the SI unit being a coulomb). The watt hour (W.h) is a unit of measurement for electrical energy (the SI unit being a joule).In the case of cells and batteries, if you multiply its capacity (in ampere hours) by the voltage, then you'll have its capacity in watt hours.
What is definition of ah efficiency of battry?
ampere hour unit of battery
How many amps equal one amp hour?
You can't convert amperes to ampere-hours, for the same reason that you can't (for example) convert kilometers to kilometers per hour, meters to square meters, etc. Those are, quite simply, incompatible units. An ampere is a unit of electrical current; an ampere-hour is really a unit of energy: the energy stored when a current of 1 ampere flows during one hour. To actually be an energy unit, a voltage must be assumed; this is usually 12 volt for a car battery.
Car batteries are normally rated in ampere-hour What does this mean?
simple. lets imagine you have a 70 Amp Hour battery (technically an accumulator, not a battery, but thats not important). the designation means it can sustain a 1 ampere continuous drain for 70 hours, or a 70 ampere drain for 1 hour. these figures are usually validated by certain temperature ranges etc,, hope this helps.
