The meaning of inductance is reviewed. Evidence is adduced that electrochemical systems may exhibit lagging currents, and it is proposed to explain this in terms of a pseudo‐inductance, which is defined as the capability of a space to store electrical energy reversibly and kinetically. The kinetic process is ascribed to the visco‐elastic behavior exhibited particularly at higher frequencies and/or in highly viscous systems as, e.g., dry‐cells. The relaxation time of ions may be calculated from the phase angle by means of visco‐elastic theory. It is suggested that the pseudo‐inductance may cancel out all or part of the capacitive time delay inherent in the transmission of nerve impulses across synaptic junctions and thus may play a significant part in such processes.
