The charge is the property associated with the matter due to which it produces and experiences the electrical and magnetic effect.
Electric charge is a scalar quantity and its SI unit is Coulomb represented as C. 1 C= 1 ampere-second. The dimension of charge is [AT].
Like charges repel each other (glass rods rubbed with wool or silk repel each other) and unlike charges attract each other (glass rod and wool attract each other).
