Detailed explanation-1: -The charge would lose potential energy as moves through the external circuit from the positive terminal to the negative terminal. The negative terminal is described as the low potential terminal.
Detailed explanation-2: -The direction of flow of electrons is opposite to direction of flow of current. Hence, the electrons move from low potential to high potential.
Detailed explanation-3: -The potential difference between points A and B, V = VB – VA, defined to be the change in potential energy of a charge q moved from A to B, is equal to the change in potential energy divided by the charge, Potential difference is commonly called voltage, represented by the symbol V or often just V.
Detailed explanation-4: -Any positive charge moves along the field lines i.e. from a region of higher to lower potential, whereas, any negative charge moves opposite to the field lines i.e., from lower to higher potential.
