Effect of wave form on let-go currents

This paper is a continuation of “Effect of Frequency on Let-Go Currents”² and concludes studies made to determine let-go currents. This paper extends the analysis to cover various wave shapes and includes a method of determining reasonably safe currents for men, women, and children, for sine waves, direct current, and complex wave forms containing both a-c and d-c components. As in previous papers, conclusions regarding reasonably safe electric currents are based on the criterion that a safe current is the let-go current for 99 1/2 per cent of a large group of healthy subjects.
