Electric Current

Electric Current Points : Electric Current, Notation, Formula, Unit of Electric Current, Definition of One Ampere, Sub Multiple Units of Ampere Definition The rate of flow of electric charge wider the influence of an applied electric field is called electric current. Notation Electric current is denoted by ‘I’. Formula If ‘Q’ is, net charge passing through any cross section of a conductor in ‘t’ seconds, then according to the definition of electric current,
Electric current = Charge/time
I=O/t Unit of Electric Current According to the formula
I = O/t = Coulomb / Second = C/Sec = Ampere Definition of One Ampere If one coulomb of charge is flowing through a cross - section of a conductor in one second then current is one ampere. Sub Multiple Units of Ampere 1 mille ampere = 10^-3 ampere.
1 micro ampere = 10^-6
