### Physics Equation of Saturday

So here is the first physics equations of whatever day I happen to get around to posting it, which happens to be Saturday. And the physics equation I chose for today is one that shows the relationship between the charge and the potential difference of a capacitor.

A capacitor is formed of any two conducting objects next to each other. When it is charged (has electricity flowing through it), each object has a charge of the same magnitude, but different signs (+ or - signs). The electricity flows from the + charged object to the - charged object and energy is stored in it.

So the equation is:

q = CV

q is the charge of each object.

V is the potential difference between the two objects. It has to do with the energy.

C is the capacitance of the capacitor (or the measure of the charge needed to produce a certain potential difference)

And that is all I am going to say about this seeing as how I now need to go solve problems using this equation for homework.

But don't electrons have a negative charge, so they flow from negative to positive? Or is like holes, moving from positive to negative?

Oh look! Mr. Geek commented ;-D
