Capacitors are two-terminal electrical components that store equal and opposite charges on conductors separated by an insulating dielectric. They were first invented in 1745 by Ewald von Kleist who discovered that charge could be stored by connecting a high-voltage generator to a glass jar filled with water. Daniel Gralath later combined multiple jars in parallel to increase storage capacity. Benjamin Franklin concluded that the charge was stored on the glass rather than in the water. Early capacitors included Leyden jars which were the main technology until 1900, though they were not as flexible as modern capacitors. The term 'condenser' was first used by Alessandro Volta in 1782 to describe devices that could store higher densities of electric
2. What Is A Capacitor?
Capacitors are two-terminal electrical elements. It is an electrical
device consisting of two conductors by an insulating or dielectric medium which carrying
equal and opposite charges.
3. History:
1) In October 1745, Ewald Georg von Kleist of Pomerania, Germany,
found that charge could be stored by connecting a high-voltage
electrostatic generator by a wire to a volume of water in a hand-held
glass jar.Von Kleist's hand and the water acted as conductors, and the
jar asadielectric.
2) Daniel Gralath was the first to combine several jars in parallel into a
"battery" to increasethechargestoragecapacity.
3) Benjamin Franklin investigated the Leyden jar and came to the
conclusion that the charge was stored on the glass, not in the water as
othershad assumed
4. 4)Leyden jars or more powerful devices were used exclusively up until
about 1900,They weren’t moreflexibleliketoday’s.
5)Early capacitors were also known as co ndensers, a term that is
still occasionally used today, particularly in high power
applications, like automotive systems. The term was first used
for this purpose to store a higher density of electric charge than a
normal isolated conductor. It was found by Alessandro Volta in
1782.
