Electric shock can cause which of the following?

Electric shock can cause which of the following?

• A. All of the above
• B. Burns
• C. Heart problems
• D. Muscle contractions

Answer: (A)

Electric shock can transfer energy through the body in a way that can cause multiple kinds of injury. The energy dissipates as heat at the points where current enters and leaves the body, which can produce burns. It can also disrupt the heart’s electrical system, leading to arrhythmias or even cardiac arrest. At the same time, the current can stimulate nerves and muscles, causing strong, involuntary contractions that may throw the person or cause additional injury. Because any of these outcomes are possible, choosing all of the above best reflects the range of effects electric shock can have. The exact injuries depend on how much current flows, whether it’s AC or DC, how long it lasts, the path the current takes through the body, and the body’s resistance (wet skin lowers resistance and increases current).
