Atom consist of electrons, protons and neutrons. Copper Atom has one free electron in its outermost shell, which can be easily moved out from nucleus by small Electro Motive Force. Static electron has negative charge, which is measured in "Coulomb"
1 Coulomb = 6.2 x 10 power 18 electrons charge.
This is the measure of static charge and associated with it Electro Static Discharge place significant role in Design of IC. When this charge moves we say "Current" and measured in "ampere".
1 Ampere = 1 Coulomb / 1 sec.
Understand Current From Production Perspective :
Chemical Reactions:-
Lead - Lead Oxide - H2SO4 Secondary battery produces 2.1 V electo motive force.
Battery duration can be increased by increasing geometry but voltage is increased by
multiple batteries only. Nickel-Cadmium secondary battery sources power to latest
mobile bcoz of its small form factor.
The current so produced is known as "Direct Current or DC".
Generator and Alternator:-
Greeks found magnite ore (rock) able to lift small iron pieces. They called it
magnetism and magnet.
