Electric current

Vedclass · Answer

(A) scalar quantity is defined as a physical quantity that has only magnitude and no direction. Electric current has both magnitude and direction,but it does not follow the vector laws of addition (like the parallelogram law). Instead,it follows the algebraic rules of addition. Therefore,electric current is classified as a scalar quantity. In contrast,velocity,force,and acceleration are vector quantities because they possess both magnitude and direction and obey vector addition laws.
