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 electrical conductivity, because of the salt to water ratio. J. P. Michaud, 1991, also said this. When using an ohmmeter, the testing processes are simple. The sensor simply consists of two metal electrodes that are exactly 1.0 cm apart and protrude into the water. An electrical current (I) flows through the water due to this voltage and is equal to the concentration of dissolved ions in the water. The more ions, the more conductive the water is, resulting in a higher electrical current, where as if the flows current is lower over the gap, which indicates a lower amount of electrical conductivity.

Restated and summed up, concentration of salts results in higher electrical conductivity.

Units for electrical conductivity are called microSiemens per centimeters. M. L. Moore, 1989, states this. One-thousandth of a Siemen/cm is called a milliSiemen per centimeter, and 1/1000 of a milliSiemen per centimeter is a microSiemen per centimeter.

He also says that the total dissolved salts in mg/L are the weight of material left behind after filtration. The temperature that specifically is used to test electrical conductivity is twenty - five degrees Celsius. Watanabe, Okano, and Masuda, 2001, said this. Ferro electric materials can create an electric field, just as magnets can create a magnetic field. When using a conductive electric field, you can polarize the Ferro electric crystals just as...
