Electrical Resistance and Ohm`s Law
... This is due to friction between the charges and the molecules that make up the conductors in the circuit and loads. The ability of a conductor to slow down or impede the flow of electricity is referred to as resistance. The loss of electric potential difference due to resistance is called the ...

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.
