Conductors [ch. ix is independent of the amount of current. In general, however, the resistanceof a conductor varies with the temperature, and for some substances, of whichselenium is a notable example, it varies with the amount of light falling onthe conductor. The Voltaic Cell. 342. The simplest… … Fig. 95. A, B o( different materials, placed in a liquid which acts chemically on atleast one of them. On establishing electrical contact between the two endsof the conductors which are out of the liquid, it is found that a continuouscurrent flows round the circuit which is formed by the two…
