Question

Define potential difference and write its S.I. unit?

Answer 1

Answer:

the difference of electrical potential between two points is potential difference.

Volt (V) which is also equal to Joule per Coulomb (J/C).

Answer 2

Answer:

The standard metric unit on electric potential difference is the volt, abbreviated V and named in honor of Alessandro Volta. One Volt is equivalent to one Joule per Coulomb. ... Because electric potential difference is expressed in units of volts, it is sometimes referred to as the voltage.
