Problem 82

BIO Standard electrocardiography measures time-dependent potential differences between multiple points on the body, giving cardiologists multiple perspectives on the hearts electrical activity. In contrast, Fig. 22.26 is a snapshot showing a more detailed picture at an instant of time. The lines are equipotentials on the surface of a human torso, associated with the hearts electrical activity. Relative to the line marked V = 0, the potential is negative to the upper left (black) and positive to the lower right (color). From the equipotentials, you can infer that the hearts electrical structure resembles that of a a. uniform charged sheet. b. dipole. c. point charge. d. uniformly charged sphere
