# Capacitance Addition Formula Origin

Hello,

Could someone help me find a general derivation of the formula for addition of capacitance of conductors? I'm hoping to find something that could be applied to a general assortment of conductors, not just parallel plate capacitors.

I look forward to your response,

Pete

If you mean capacitance between conductors, or capacitance from conductor to ground, it is not a function of the conductor itself, but rather a function of the geometry and the distances.
