But it must not be forgotten that this 25 per cent, represents simply the auerage current passing through the body, and by no means repre- sents the maximum. In any given cross section of a conductor formed of two substances, having different specific resistances and placed in parallel with one another, the proportion of the total cur- rent taken by each branch will vary directly, as
