The full strength of both batteries should be applied to the attachment atthe element board, that is, assuming the rheostat is sufficiently powerfulto thoroughly control them. In the case of a strange instrument being usedfor the first time, this must be experimentally ascertained. This is simplyeffected by introducing the full resistance into the circuit, and by increasingthe battery current till a minimum
