A Galvanometric Method of Measuring Electrolytic Resistance

Abstract

THE ordinary laboratory bridge method of measuring electrolytic resistance employing a telephone is somewhat unsatisfactory, owing to the difficulty of accurately judging the position for minimum sound in the telephones. Experiments made by different observers are, for this reason, often liable to give results which vary considerably. A method in which the telephone is replaced by a galvanometer possesses, therefore, a decided advantage, and the following simple device, which I have not seen described elsewhere, has been found quite satisfactory for ordinary purposes.
