Coulomb Meter Digital Instruction Sheets
... The Coulomb meter is a digital instrument that can replace the traditional electroscope. It measures electrical charge or the quantity of electricity. By definition, one Coulomb is the quantity of electricity equivalent to 1x amp second (one amp flowing for exactly one second). The amount of charge ...

... The French physicist, Andre-Marie Ampere (1775 - 1836) set up two parallel wires. One of them was free to move sideways, back and forth. When both of the wires carried current in the same direction, they attracted each other. If the current flowed in opposite directions, they repelled each other. He ...

... But our rational function tells us that to carry electricity over large distances (large l ) we need large voltages (large V) if we want the power line radius r to be small (Figure 1.2). And this was precisely Edison’s problem; his power plants operated at the low voltage of 110 volts. The result: c ...

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.
