Lecture 7: Electrostatics
... Conductors / Insulators. It can happen that when certain substances come in to contact some outer shell electrons transfer from one substance to the other. In this case one substance looses electrons and the other gains electrons. Negatively charged bodies have an excess of electrons and Positively ...

... 1) Before connecting this circuit, we will measure the resistance of 2 wires that differ only in their length. Using a multimeter, measure the resistance of the thin 30 cm nichrome wire (the middle wire on the green board). Write your measurement in the Resistance column of the table. Repeat for 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.
