... 2. A Gaussian surface is not a physical surface. It need not coincide with the boundary of any physical object (although it could if we wished). It is an imaginary, mathematical surface in the space surrounding one or more charges. 3. We can’t find the electric field from Gauss’s law alone. We need ...

... There are two types of current – Direct Current (DC) and Alternating Current (AC) Direct Current (DC) – current where charge flows only in one direction (ex. Batteries) Alternating Current (AC) – the flow of electric charge that regularly reverses its direction (ex. outlets) Charge flows more easily ...

History of electromagnetic theory
For a chronological guide to this subject, see Timeline of electromagnetic theory.The history of electromagnetic theory begins with ancient measures to deal with atmospheric electricity, in particular lightning. People then had little understanding of electricity, and were unable to scientifically explain the phenomena. In the 19th century there was a unification of the history of electric theory with the history of magnetic theory. It became clear that electricity should be treated jointly with magnetism, because wherever electricity is in motion, magnetism is also present. Magnetism was not fully explained until the idea of magnetic induction was developed. Electricity was not fully explained until the idea of electric charge was developed.
