what is meant by dielectirc medium?
what is the dielectirc value of air and water???
Answer Posted / sidharth
Dielectrics are insulators. Only when the applied field across the medium is very high i.e. greater than the breakdown voltage of the dielectric, the dielectric breaks down, thus losing its prime property. SO, i think it cannot be called a 'partial conductor' since it is forced to conduct, not naturally.
Dielectric strength of dry air is 30kV/cm
" " " moist air is 10kV/cm
Water is a pure conductor.
