FAQs about The difference between capacitors and wires
What is the difference between a capacitor and a wire?
The wires have a relaitvely small effective area, and are much farther apart than the capacitor plates, so the capacitance between the wires will normally be much less than that of the capacitor. 1) If the wires are right beside each other (like in a circuit board), the distance is around the same as a capacitor.
Why does the equation for capacitance not take the position of wires?
Since the whole thing acts as one big capacitor, the charge wouldn't just gather at the capacitor, it would spread out over the whole wire and the capacitor, meaning there would be less charge in the capacitor. And if this is true why doesn't the equation for capacitance take the position of the wires into account?
Do two wires make a capacitor?
