Ampere (ampere) is the basic unit of electric current in the International System of Units, referred to as ampere. Symbol A. Named in memory of French physicist A. Ampere.
The conversion relationship between ampere and other current units is: 1 ampere is equivalent to 3×109CGS electrostatic current unit (esu). 1 ampere is equivalent to 0.1 CGS electromagnetic current unit (emu).
Electricity is a natural phenomenon, which refers to the phenomenon brought about by the movement of electrons. Lightning in nature is a phenomenon of electricity. Electricity is a property of the repulsive and attractive forces that arise between subatomic particles like electrons and protons. It is one of the four fundamental interactions in nature. There are two kinds of electron movement phenomena: We say that atoms lacking electrons are positively charged, and atoms with excess electrons are said to be negatively charged.
