Electrical conductivity estimates the amount of total dissolved salts, or the total amount of dissolved ions in the water. EC is the abbreviation of electrical conductivity, and TDS is the abbreviation of total dissolved salts. This is stated by numerous sources, including J. P. Michaud, 1991. Conductance is the opposite of resistance. When water is evaporated, the remaining salts left behind are now more concentrated in the lesser amount of water, leaving there to be more …

…than metals. The best-known semi-conductor is silicon. The Department of Chemistry and Biochemistry, 1997, says that it is possible to increase the conductivity of a semi-conductor by implanting foreign atoms into an otherwise pure material. This is referred to as doping, and the atoms used are dopants. This ends up making two different kinds of semi-conductors: n-type and p-type. N-type semi-conductors are completely natural, where as P-type semi-conductors are impure, they have atoms planted in them.
