Conductivity
of a matter is offering very important information about an electronical
property. To determine this experimentally, you have to measure a resistance
very precisely and correctly. Wheatstone bridge is usually used for this. This
experiment to help you to learn how to use wheatstone bridge and its structure
and to measure an electrical resistance.
