If exposure involves 0.005 amps, what sensation is most likely?

• A. Slight shock
• B. Loss of muscle control
• C. Death
• D. Painful shock

Answer: (D)

When current passes through the body, the sensation rises with the amount of current. Five milliampere (0.005 A) is enough to produce a noticeable, painful shock for most people. It’s above the level that causes a faint tingling at lower currents, but well below the levels that cause muscle paralysis or lethal heart effects. The terms “slight shock” and “death” refer to much smaller or much larger currents, respectively, with severity also depending on how long the exposure lasts and the path through the body. So the most likely sensation at 0.005 A is a painful shock.
