PHY222, Elements of Physics II
Wheatstone Bridge, 8 February 2008

Theory Guidance:

1. Describe the principle of operation of the Wheatstone circuit. Keep the discussion for this section VERBAL - save an algebra proof for the hand-written sample calculation in the results section.
2. Look up an application of the circuit in measuring resistances, especially in any situations where a store-bought Ohmmeter wouldn't work. This does not need to be detailed; a sentence-long description is all that's necessary, along with the proper citation to direct the reader to more information.

Comments on the Procedure:
The procedure is given in the lab manual. In your write-up, SUMMARIZE the major steps in the measurements. Identify as usual what you are measuring (and how), and what elements you are controlling. DO NOT clone the lab manual (or other sources) - read the procedure, digest it, summarize it concisely.
It would also be a good idea to list anywhere you identify as a potential problem or question that could come up during the experiment. This is certainly optional, but if, as you read the procedure, there is a step that doesn't make sense yet, go ahead and say so in the write-up.
