Answer:
c)From high potential to low potential.
Explanation:
Given that
current is flowing through resister.
As we know that those quantity have direction as well as magnitude then these are called vector quantity and those quantity have only magnitude then they called scalar quantity.
As we know that current have direction as well as magnitude so current is a vector quantity.
Current flows from high potential to low potential.
