    I hope you know that the per second means divided by seconds and the -seconds means multiplied by seconds.

    Well the volt-second is another name for the unit of magnetic flux, the Weber.

    http://en.wikipedia.org/wiki/Weber_(unit)

    Volts per second is the time rate of change of voltage dv/dt.
    So it is the slope of a voltage time graph, or the derivative of a voltage time function.

    yet not answered for volt-sec.ist that both related to charging and discharging stuff."AA battery holds about 2.8 amp-hours."what does it mean.explain me detially.thank you in advance

    If you draw 1 amp from that battery, it will last 2.8 hours.
    If you draw 2.8 amp from the same battery, it will last 1 hour.

    i think i am trigerred
    1)2amp/hr means it produce 2 amp evry hour
    2)2 amp-hr mean it discharges 2 amp in hour
    am i right

    You should start a new thread for a new question.

    Let us finish with the first question first.

    What did you not understand?

    U-oh ... Infinite loop
    Vs => Ah => As => Kmh => Wait ... what? Kmh? That's silly. Give me an example of Kmh?

    To answer the question about A/s and As.
    When you have a imaginary setup of 1V over 1 Ohm. there is 1 A/s flowing. That means it is happening now and you are measuring it. Every second there is one Amp flowing.
    If you have an imaginary battery of 1 As that means it has a capacitance (it is capable) of 1 Amp for 1 second. It can deliver you 1 amp for one second OR(!) it can deliver you 0.5 amp for 2 seconds. It depends how much you need at one given time.

    Hope it clears this out.

    yes its cleared me
    when something in multiplication with time.it means some energy is available to do work
    thanks
    thank u so much for patience.and sorry for my poor english
