Potential difference (V) between two points = Work done (W)/Charge (Q). Electric Potential is defined as the amount of work done when a unit positive charge is displaced from infinity to a point inside the electric field. potential energy, stored energy that depends upon the relative position of various parts of a system. What is the SI unit of electric potential class 10? Electricity Class 10 MCQs Questions with Answers Question 1. Necessary cookies are absolutely essential for the website to function properly. The unit of potential is volt, named after a scientist Alessandra (1745-1827). Recall that the electric field strength is defined in terms of how it is measured or tested; thus, the test charge finds its way into the equation. Functional cookies help to perform certain functionalities like sharing the content of the website on social media platforms, collect feedbacks, and other third-party features. Electric potential is the potential energy per unit charge. The constant of proportionality k is called Coulombs constant. The S.I unit of electric potential is joule/coulomb or volts. Solution : The S.I unit of electric potential is volt. Electrostatic potential energy is fundamentally a measure of the strength of the nearby charges, nuclei and electrons, at a particular position. Here we have given NCERT Class 10 Science Notes Chapter 12 Electricity. Electric potential is electric potential energy or work per unit of charge. The cookie is used to store the user consent for the cookies in the category "Performance". Electric potential is also simply known as potential. = 10 V 5 C. Energy= 50 Joule. To accurately analyze the charge distribution of a molecule, a very large quantity of electrostatic potential energy values must be calculated. October 9, 2022 by George Jackson. What are the topics in General Physics 2? One ohm is equal to the resistance of a conductor through which a current of one ampere flows when a potential difference of one volt is applied to it.
