Answer to Question 1

ANS: A
In these cases, the third (ground) wire prevents the dangerous buildup of voltage that can occur on the metal frames of some electrical equipment.

Answer to Question 2

ANS: A
Higher currents (exceeding 100 mA) that pass through the chest can cause ventricular fibrillation, diaphragm dysfunction (due to severe, persistent contraction), and death. Table 3-1 summarizes the different effects of these two types of electrical shock.
