Introduction to Electronics:
1745 Cuneus and Muschenbrock,
in Leyden (Netherlands), discover the Leyden jar.
The first
electrical capacitor - a storage
mechanism for an electrical charge. The first ones were a
glass jar filled with water -two wires suspended in the
water. Muschenbrock got such a shock out of the first jar he
experimented with that he nearly died.
Later, the water was replaced with metal foils wrapped
so there was insulation between the layers of foil- the two
wires are attached to the ends of the sheets of foil. This
gave birth to Modern Electronics.
Definition of electronics:
Electronics
is
the branch of
science that deals with the study of flow and control of
electrons (electricity) and the study of their behavior and
effects in vacuums, gases, and semiconductors, and with
devices using such electrons. This control of electrons is
accomplished by devices that resist, carry, select, steer,
switch, store, manipulate, and exploit the electron.
