Question

What is Potential difference ??

Answer 1

$\huge{\tt{\red{}\green{A}\purple{N}\pink{S}\blue{W}\orange{E}\red{R}}}☘$

Volt, unit of electrical potential, potential difference and electromotive force in the metre–kilogram–second system (SI); it is equal to the difference in potential between two points in a conductor carrying one ampere current when the power dissipated between the points is one watt.

Answer 2

Potential difference between any two points is defined as the amount of work done in moving a unit charge from one point to another.

SI Unit = Volt ( V )
