Formula for potential difference in physics
WebWhere V A and V B is the electrostatic potential of the particle at points A and B, respectively, U A and U B are the potential energy of the particle at points A and B. Q is the magnitude of the charge.. As we know, the actual value of the potential at any point holds no significance, and we would rather calculate the potential difference between two … WebThe 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. 1 volt= 1 joule/ 1 coulomb Unit for measuring the potential difference is volt and instrument used for measuring potential difference is a voltmeter .
