Excerpt from Practical Electricity: A Laboratory and Lecture Course for First Year Students of Electrical Engineering, Based on the Practical Definitions of the Electrical Units

A new edition of the book being required, advantage has been taken of the occasion to bring the work up to date. Also to modify, where convenient, the symbols used, in accordance with the list adopted by the International Electrotechnical Commission in 1913. A copy of this list is given in Appendix vh.

The sections on Dry Cells have been rewritten, and that dealing with Storage Cells amplified. The addendum to Appendix I, relating to the practical electrical units, has been revised and extended to include more recent work in this subject.

I am again indebted to Mr. Maurice Solomon, of the General Electric Company, for valuable information; to Mr. R. W. Cooper, m.a Messrs. Benn Brothers, and Edison Accumulators, Limited, for the use of blocks; and to the India Rubber and Gutta Percha Company. My best thanks are-also due to Dr. Chas. Chree, m.a., for magnetic data, and to Mr. F. E. Smith, for help in connection with absolute measurements of the primary electrical units. The whole world is deeply indebted to Mr. Smith for the masterly way in which he has originated and carried out the researches on electrical standards at the National Physical Laboratory for many years past. His work has placed Britain well ahead of other nations in this branch of precision measurements.
