hi every body ...
we all know that the capacitance of a capacitor (C) of a parallel plate area of (A) far away of (d) is given by the equation: C = Ae\d where e is the permitivity constant ...
and when using a dielectric material, the capacitance is multiplied (k) times, where k is the dielectric constant ...
My question: what are the factors that affect the value of k.
Also I have another question: we all know that a bettary is a voltage source, but is the current source a real device, and if so, is it a bettary or what, or it is a special case of the voltage source ... please help
thanks
