Worked examples

Electric potential and electrostatic energy

One sheet for each type of problem, with several worked examples of increasing difficulty: first the computation, then the explanation in words. Each sheet starts with links to the theory it uses.

• 1Potentials of systems of point charges
• 2Work done by the electric force and potential differences
• 3Charged particles accelerated by potential differences
• 4Electrostatic energy of systems of charges
• 5Potential of continuous charge distributions
• 6Potential of distributions with spherical and cylindrical symmetry
• 7Electric fields obtained from the potential
