CONDUCTIVITY

The following questions are to be answered by building pages in a Wiki book for use in this course. All questions for exams will be taken from the power points I go through in class and your books.

1.	Define electrical conductivity? 2.	What is the difference between conductance and conductivity? 3.	What is another name for electrical conductivity? 4.	How does conductivity relate to resistivity? 5.	What are the SI units of conductivity? 6.	What is a Siemen and where did it come from? 7.	What types of materials have a high conductivity and low resistance? Low conductivity and high resistance? 8.	Explain how water can be defined as pure based on its conductivity, or specific conductance. 9.	Give some examples of the electrical conductivities of some materials along with the units and notes to go along with each material. 10.	How is electrical conductivity dependent on temperature? Explain. 11.	 How are electrical conductivities compared when they occur at different temperatures? 12.	What is the temperature slope for naturally occurring waters? 13.	How is this graph plotted? 14.	Define superconductivity. 15.	 Define electrical resistance. 16.	 What is the mathematical equation of the resistance of an object? 17.	What is a resistor? 18.	 What is a Wheatstone bridge?
