In simpler terms, capacitors are physical devices, while capacitance is a measure of the charge storage capacity of a capacitor. The term "capacity" typically refers to the ability to hold or contain something, often in a broader context. In contrast, a capacitor specifically refers to an electronic component used to store electrical energy.
