ELECTRIC CHARGE, CONDUCTORS AND INSULATIONS
... The potentiometer is an instrument that can be used to measure the emf of a source without drawing any current from the source. It balances an unknown potential difference against an adjustable, measurable potential difference. The principle of the potentiometer is shown in the figure below. A resis ...

ELECTRICAL PRINCIPLES, TERMINOLOGY, AND SAFETY
... Electricity* can be defined in several ways. The layman defines electricity as a form of energy that can be converted to light, heat, sound, and motion. Electrical engineers define electricity as the flow of electrons from one atom to another. This flow of electrons is controlled in an electric circ ...

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.
