A conductor AB is joined to a cell with its end A at a low potential and the end B at a high potential. The direction of flow of current in the conductor is from A to B.
(a) State whether the current is a scalar or vector? What does the direction of current convey? (b) State whether the potential is a scalar or vector? What does the positive and negative sign of potential convey?
Current in a circuit flows :
(a) in the direction from high potential to low potential
(b) in the direction from low potential to high potential
(c) in direction of flow of electrons
(d) in any direction.
