Modern applied chemistry requires the use of highly specialized instruments. Among these is the capacitance bridge. This bridge, as a tool of the chemist, is little understood. It is the purpose of this thesis to present the theory of capacitance bridges. This can best be accomplished by actual construction of one directly from the theory. The first part of the thesis is devoted to alternating current theory. This is to acquaint the reader with the barest fundamentals. The second part deals with the methods of measurement of dialectric constant, pointing out the advantages of each method. The third part deals with the construction of the bridge and its associated equipment. The author has had training in electronics while in the service. However, electronic theory has been omitted from this work since it is not the essential theory of capacitance bridges.
