In a hiring freeze, an employer decides to stop hiring employees for all non-essential positions. It allows an employer to consolidate current employees and potentially restructure departments to complete the work that is essential for serving the customers of the business.
Since the electrical conductivity is a measure to the capacity of water to conduct electrical current, it is directly related to the concentration of salts dissolved in water, and therefore to the Total Dissolved Solids (TDS). Salts dissolve into positively charged ions and negatively charged ions, which conduct electricity.
Conductivity is water's ability to allow the flow of electricity and is defined as the reciprocal of resistivity, which is water's opposition to the flow of current. Water's conductivity is directly proportional to the amount of ions in the water. The more ions in the water, the higher the level of conductivity.
