Since force is a vector, the electric field too is a vector quantity. Current has two types, direct and alternating; the direct current has a constant direction; meanwhile, the alternating current alters its direction with time. When two currents meet at a point the resultant current will be an algebraic sum. Electric field is zero in that point because the sum of electric field vectors have same intensity and direction, but are . Electric intensity is -A. a scalar quantityB. Scalar quantities have the same value regardless of their direction, so they cannot be resolved. Is electric charge a vector or scalar?

Using the cosine or sine of adjacent angles, you can resolve vector quantities in any direction. The ampere, symbol A, is the SI unit of electric current. ; if the quantities have the same unit, they can typically obey algebraic law. In a direct current (DC) circuit, current flows in one direction only, and one pole is always negative and the other pole is always positive. Quantities with magnitude, unit, and a particular direction are called vector quantities, so when defining a vector quantity, you must know its specific direction and the magnitude value. Starting with the premise that the electric charge associated with fundamental fermions (quarks and leptons) can, under certain circumstances, be appropriately represented as a real \emph{internal} 2-vector, the mathematical ``machinery'' implicit in the associated internal 2-space is shown to apply to \emph{all} fundamental fermions.

Today, electron paths are no longer described as paths, but are now called clouds of electrons. In physics (and this is a physics question), charge is a scalar rather than a vector or a tensor. Quantities with magnitude, unit, and a particular direction are called vector quantities. Why do you have to swim between the flags?
