= electric potential

= change in potential energy (or simply )

Electron (proton) mass = 9.11×10−31kg (1.67× 10−27kg). Elementary charge = e = 1.602×10−19C.

=kinetic energy. 1 eV = 1.602×10−19J

near isolated point charge

Many charges: .

The alpha-particle is made up of two protons and two neutrons.

defines capacitance.

where A is area and d<<A1/2 is gap length of parallel plate capacitor

 

= stored energy

= energy density
