Question

what do you mean by the capacitance of a conductor?

Answer 1

Capacitance is the ability to store electrical energy. Almost all things, including you, can store some electrical energy and therefore have capacitance. When you rub your feet across a carpet, charged particles called electrons can be transferred from the carpet to you. When positive and negative charges are separated, the stored electrical energy increases. The charges you have picked up from the carpet give you electrical energy that you store until you touch something like a metal doorknob or another person that allows the energy to be released. You feel this as a mild shock as the energy leaves your body.

Answer 2

Capacitance, property of an electric conductor, or set of conductors, that is measured by the amount of separated electric charge that can be stored on it per unit change in electrical potential. ... Capacitance also implies an associated storage of electrical energy.
