the battery has a positive and negative potential.so it must be a natural tendency of electron to flow from the higher concentration to lower concentration but that does not happen in practice explain?
Answers
Explanation:
Electrons can move by the action of the electric force, or the magnetic force. In the case of the electric field, it is established, by covenio, that regions around the positive charges are considered high potential, and regions around the negative charges, low potential.
Since electrons are negative they should be repelled by the negative charge and attracted by the positive charge, that is, in an electric field the electrons must move from regions of low potential to the regions with high potential by the action of the electrical forces.
In a battery, the chemical process separates the positive and negative charges so that a concentration of positive charges on the positive pole and a concentration of negative charges in the negative occurs. When the battery is connected to a circuit, an electric field is created inside the wires and electrons (the only ones that can move in metals) are repelled from the negative pole (region of low potential) and attracted by the positive (region of high potential).
