A substantial reduction in skin resistance (SR) is produced by a rise in induced voltage. This indicates that with a constant‐current circuit, variations in voltage can have a significant effect on the SR level. Therefore, SR levels obtained with a constant‐current and constant‐voltage circuits were compared for a group of S s. The higher the SR level, the greater the discrepancy between the constant‐current and constant‐voltage measurements. The use of a constant‐voltage circuit when measuring high SR levels is recommended.
