The electromotive force (open-circuit voltage) produced by a cell is a function of the materials used in the manufacture of its electrodes, and has nothing whatsoever to do with it physical size.
Volt-ampere (VA) is a measurement of power in a direct current ( DC ) electrical circuit. The VA specification is also used in alternating current ( AC ) circuits, but it is less precise in this application, because it represents apparent power , which often differs from true power . In a DC circuit, 1 VA is the equivalent of one watt (1 W). The power, P (in watts) in a DC circuit is equal to the product of the voltage V (in volt s) and the current I (in ampere s): P = VI. In an AC circuit, power and VA mean the same thing only when there is no reactance .
