Explain how electric current flows from high to low potential

how electric current flows from high to low potential?

Answer 1

Every metallic wire consists of electrons, therefore when the two ends of the circuit is connected to the battery then the battery generates an electric field in the wire. This electric field forces the free electrons to move toward the high potential (positive terminal) of the battery from the low potential (negative terminal) of the battery.

It is because that the two ends of the wire are at different potentials and there is a potential difference across them. As metals have a number of free electrons therefore these electrons will move from lower potential terminal to the higher potential terminal and the current will move from high potential to low potential.
