Electric potential of charge distributions | AP Physics | Khan Academy

Electric potential describes the electric potential energy per unit charge at a point in space. Expressions for the electric potential of charge distributions can be found using integration and the principle of superposition. Sections: 00:00 - Potential due to discrete charges 00:40 - Continuous charge distributions 01:47 - Comparing potential and field integrals 03:16 - Potential at the center of a charged ring 05:31 - Setting up the integral for a charged rod ------------------ Khan Academy is a nonprofit organization with the mission of providing a free, world-class education for anyone, anywhere.
