We use narrow, high purity copper wires as these can carry current, but as they are so narrow (100 microns) they don't carry too much heat, it is still a trade off.<BR><BR>Now if you wanted good ...

Electrical current flows easily through a conductor, but does not flow through an insulator. Find out more with BBC Bitesize. For students between the ages of 11 and 14.

Dr. Yindi Jing, an Associate Professor in the Department of Electrical and Computer Engineering at the University of Alberta in Edmonton explains that water is not a good conductor of electricity ...

Water is also a conductor despite not being a metal. Some materials, such as wooden corks are good electrical and thermal (heat) insulators. Gases are generally poor electrical conductors.

The kite string or as popularly known as ‘Manja’, is a good conductor of electricity and can transmit very high voltage if it touches the overhead live wires or even enters the arching zone.
