Other Electrical Effects

Static Electricity

Electrons can get separated from atoms and accumulate on insulators. The resultant charge can build up to thousands of volts. Static electricity causes the little sparks one produces from walking across a dry carpet. The repelling force of the electrons causes the “hair standing on end” effect. Static electricity also causes lightning, but with much higher voltages and currents (millions of volts and amperes).

Coupling

An electrical current in a wire close to another wire can affect the electrons in the second wire. This coupling is due to the electrons' repelling force and to the electromagnetic effect of moving electrons. The faster current changes occur in the first wire, the more effect there is ...
