Charge and electric flux
... • Roughly speaking we can picture the ΦE in terms of the field lines passing through A. increasing the area means that more lines of E pass through the area, increasing the flux • Stronger field mean more closely spaced lines of E and therefore more lines per unit area so again the flux increases ...

... Charge is the fundamental quantity that underlies all electrical phenomena. The symbol for charge is q, and the SI unit for charge is the Coulomb (C). The fundamental carrier of negative charge is the electron, with a charge of – 1.6 x 10-19 C. The proton, found in the nucleus of any atom, carries e ...

... The diagram shows a circuit with a single battery and a single bulb. Note that a complete and unbroken path is present that allows electrons to flow from the negative end of the battery, through the bulb, then back to the battery entering the positive end. Because there is only one path for the elec ...

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.
