... Fortunately for us, the resistance of dry skin is a very important protection at low voltages. Typically, over an ordinary contact area, the skin inserts 10 100 k between an outside conductor (like the end of a banana lead or multimeter probe) and the internal body fluids. Therefore, at voltages be ...

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.
