CURRENT "Electric
current is defined as the amount of electric charge passing through a
cross section of a conductor in unit time." In
other words "The
rate of flow of electric charge through a cross section of a conductor
is called Electric Current". Mathematically: Electric
current = electric charge / time I
= Q / t
UNIT:
Unit of electric current is AMPERE. 1
ampere = 1 coulomb / 1 sec DIRECTION
OF CURRENT There
are two types of current. ELECTRONIC
CURRENT Electronic
current flows from negative to positive terminal. CONVENTIONAL
CURRENT Direction
of conventional current is taken from higher potential to the lower
potential. |
