Simulation 3: Liquid Conductivity

Some materials have a certain amount of conductivity, or ability to conduct electricity. The conductivity of a material is the opposite of its resistivity, or resistance. These materials can take either solid or liquid form. In the window demonstration, a beaker of conductive material is used to complete the circuit. By modifying the liquid level, study the effect of the liquid level on the voltage. What does this imply about the conductivity of air? Also, include salt or acid in the liquid and determine the effect (to do so, just click on NaCl for salt or the test tube for acid).
