On the present curves the effect of using only half the control is shown, but this was not carried beyond 15 amperes owing to this being the limit of range of the instrument in use. The curves(d)also show the effect of inserting equal small resistances in the control circuits, and curves C for correct connections. dotted Control currents are shown in cases (b), (c) and (d).
