A potentiostatic method to permit determination of double layer capacity of electrodes under dynamic conditions has been developed. Small potential pulses are superimposed on a d‐c sweep and the capacity is determined from the magnitude of current changes observed at the initiation and cessation of the pulse. Further, a method utilizing a transistor is described which permits rapid switching of a potentiostat from galvanostatic to potentiostatic operation.
