Explanation:
potential difference
It is an amount of work done to bring unit positive charge between two points in an electric field.
potential difference is also called as voltage.
SI units of voltage is "volt".
In ohms law
the potential difference between two terminals of
a conductor is directly proportional to the amount of current at a constant temperature .
potential difference formula.
V=IR
V= potential difference
I= current
R= constant term
