Energy in case B and C is generally written in eV because in theses two cases energy is very less
A common unit used to measure the energy of small particles is the electron volt (eV),...
The electron volt (eV) is a convenient unit of energy for expressing atomic-scale energies. It is the amount of energy that an electron gains when subjected to a potential of 1 volt; 1 eV = 1.602 ✕ 10−19 J. Using the Bohr model, determine the energy, in electron volts, of the photon produced when an electron in a hydrogen atom moves from the orbit with n = 3 to the orbit with n = 2.

Electrial Potential of a Battery oc It increases the potential of the battery Learning Goal: To understand electrical potential, electrical potential energy, and the relationship between them. Submit Previous Answers Correct Electric potential and electric potential energy are related but different concepts. Be careful not to confuse the terms. Electrical potential energy UE is the potential energy that a charge q has due to its position relative to other charges. The electric potential V at a specific position is a...
