24. Electrostatic Potential
Potential difference and electric potential:
DU = qo DV
U is the electric potential energy.
Try to build a feeling for the Electric potential and potential
energy due to one charge, two charges, …
Potential differences in a uniform electric field:
|DV| = E d
The concept of equipotential surface:
Equipotential surfaces for a charge or a set of charges
Equipotential surfaces for spherical, cylindrical and ‘flat’
charge distributions
E = -V
Electric potential due to continuous charge distributions:
V = kdq/r
A charged conductor constitutes an equipotential.
