Question

Quizplus · Accepted Answer

A galvanometer is commonly used in the field of psychophysiology to measure changes in electrical conductance of the skin known as electrodermal activity (EDA). EDA is known to be affected by emotional arousal, making galvanometers useful in measuring emotional responses. Therefore, option B is the best choice. The other options (A, C, D, E) are incorrect because they do not relate to the function of a galvanometer.
