The author has felt that the transition from the elementary to the intermediate laboratory may sometimes be too abrupt, and that while the student is getting accustomed to the more advanced laboratory he misses some of the important points in the early experiments he performs. The experiment described is designed to accustom the student to the new level of experiments, and give him some insight into some fundamental principles of experimentation. The experiment consists of measuring a resistance by several different methods. The results are then compared, and the relative merits of the methods are discussed. The methods used are the ohmmeter, the voltmeter-ammeter method, the Wheatstone bridge, the potentiometer, and the substitution method. Details of these measurements will be discussed.
