Negative sign in answer does not mean a wrong answer. It indicates that current are in opposite direction to assumed direction.
55 V
50 V
0 V
5 V
The direction of current is opposite to the direction of flow of electrons. So does this mean current is a vector quantity? Why/why not?
If the electrons move from negative to positive terminal then why does current flows in the opposite direction
(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?
