Question

Write expression of potential difference between two points A &B



​

Answer 1

Answer:

V=Uq. The electric potential difference between points A and B, VB−VA is defined to be the change in potential energy of a charge q moved from A to B, divided by the charge. Units of potential difference are joules per coulomb, given the name volt (V) after Alessandro Volta. ... ΔU=qΔV.Nov 5,

Answer 2

Explanation:

The potential difference between two points is said to be 1 volt if the work is done in moving 1-coulomb charge from one point to other is 1 joule. Unit for measuring the potential difference is volt and instrument used for measuring potential difference is a voltmeter.
