Excerpt from Laboratory Manual; Direct and Alternating Current: Prepared to Accompany Timbie's Elements of Electricity
This book of laboratory directions is designed for the use of students in courses other than that of Electrical Engineering, who take a brief amount of work in the fundamental principles of electricity.
The object of the laboratory work in such cases is to aid in the understanding of the theoretical and practical items given in the recitation and lecture room. It is the purpose, therefore, to eliminate in as far as possible all features in the actual work of the laboratory which would tend to lessen or detract from concentration upon the underlying principles involved in the experiment in hand.
To facilitate the work, each experiment is prefaced where possible by an assignment of articles in the text book which bear directly or indirectly on the experiment in question. Further, in a part of the experiments, diagrams of the electrical connections will be found, together with simple forms which may be followed in the recording of observations. These forms are somewhat more complete in the first than in the advanced experiments in order to serve at the outset as a guide in the preparation of the data sheets. In the latter experiments this general scheme of ruling up the data sheet is to be followed by each group of men in the preparation of data sheets before the laboratory exercise.
After teaching with a text book which was too advanced for the students and a laboratory manual which was not suited to the text book, the students nor the equipment, it was thought best to write a Manual which should be adapted to the specific requirements of the coming year. The difficulties encountered by the student have been observed and the aim of the Manual is to present the subject from his standpoint.
