Definition of capacitance

The word "capacitance" originated from the Latin words "capere" meaning "to take" and "capacitus" meaning "capacity". In the 18th century, the German mathematician and physicist Georg Simon Ohm introduced the concept of capacitance as a way to describe the ability of a conductor to store electric charge. Ohm used the term "Capacität" in his book "Die galvanische Kette" (The Galvanic Chain) in 1827. Later, the term was translated into English as "capacitance". In essence, capacitance refers to a device or component's ability to hold a charge or store energy, allowing it to release it quickly when needed. Today, capacitance is an essential concept in electronics, electrical engineering, and countless applications that rely on storing and releasing electric energy.
