96 sec.
From these data we may now draw the three curves, as in Fig. 55,
wherein the abscissae are the values of time in seconds and the
ordinates the current. The faint vertical dotted lines mark the time
constants in the three cases. It will be seen that when rapid working
is required the magnetizing current will rise, during short intervals
of time, more rapidly if all the cells are put in series than it will
do if the cells are grouped according to the amateur rule.
