  • Level - what is Capacitance?

    An electrical parameter which physically is most easy to define, electrically often misconstrued. Physically, a capacitor is two electrical conductors separated by a non-conducting (or very high resistance) medium between the conductors. Consider the two plates of area (A) in Figure 1. The plates are metallic and they are separated by a distance (D). Figure ...
