Abstract :
A rectangular co??rdinate potentiometer circuit is described in this paper, the chief features of which are the elimination of the usual phase shifting transformer and the slide-wire type of potentiometer resistor. Although not yet available in commercial form this potentiometer has been in use in the laboratory for several years with good results, particularly in magnetic measurements at low and medium inductions and in measurements of the power factor of capacitors.
