qualto the electromotive force of the standard cell E^. Then, the junctionT, being kept in ice and water, the temperature of To may be varied,and the electromotive force of tlie couple found from the length ofwire AB necessary to produce a balance. A more convenient apparatus for the same purpose,… … Fia. 216, the current in the main circuit is adjusted by means of the rheostatsRi and Ro until a balance is obtained, and SC and SN are arrangedto be of such resistance that for the proper value of the main current,the fall of potential over 50 ohms of circuit is 1 volt. The coil MVChas 29…
