The article provides a general overview of capacitance , explaining its definition, working principle, and the factors that affect it. It also covers key safety considerations, voltage ratings, and the formula used to calculate capacitance in electronic circuits. Definition: Capacitance is a property that opposes any change in voltage. A capacitor is a device that temporarily stores an electric charge. Capacitance is the ability of a structure to store energy in an electric field. Capacitance is defined as the capacity of any material to store electric charge. The substance that stores the electric charge is called a capacitor, i.e. the ability of the capacitor to hold the electric charge is called capacitance . It is denoted with the symbol C and is defined as the ratio of the electric charge stored inside a capacitor by the voltage applied. Thus, any material that has a tendency to store electric charge is called a capacitor and the ability of the material to hold ... 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.
