Question

what is the difference between potential difference and direction of current flow ?

Please help fast as I need it tomorrow​

Answer 1

Answer:

Potential difference is the work done in bringing a unit positive charge from Infinite to a fixed point in the direction opposite to the flow of current.Or the difference in potential at two different points Such as Positive and Negative Charges in a Battery have different potiontial and create a potential difference.

And direction of flow of current means the direction in which current is flowing that is from Positive terminal to negative terminal.

Answer 2

Potential difference across two points in a circuit carrying some current is the work done to move a unit positive charge from one point to other.

Battery or cell creates that potential difference by chemical reactions and set up the free electrons inside the conductor to move in a particular direction,i.e,the direction of flow of current.

There is also one question which arise from this that electrons are negative therefore the current direction should be from negative to positive.This is not so beacuse electrons were not discovered before electricity.And now to make the phenomenon same term conventional current is used which is the hypothetical flow of positive charges that would have the same effect in the circuit as the movement of electrons actually does.
