What does potential at a point exactly mean? My teacher tells me
that current flows from higher potential to lower potential but
when I ask him the reason, he fails to give me a convincing
answer. And can anyone explain how electric potential is related
to potential energy & work done? Further, when I referred a
Physics textbook it said that since Coulomb's force &
Gravitational force are mathematically similar, electric
potential is a charge's equivalent of a the potential energy of
mass. Hence I related Electric potential to the potential energy
of a ball for example. A ball falls from a height to the ground
because of Potential energy- so similarly, current flows from
higher to lower potential. Is this analogy correct? Even if the
above analogy is correct, I still cannot understand why current
flows between two electrodes of an electrochemical cell. The
only explanation my teacher offers is that there is a potential
difference & thus current flows from higher to lower potential.
This explanation is not of
