A worker feels a mild shock at constant voltage and the grip tightens. What happens to the severity of the shock?

  1. It stays the same, because the supply voltage is constant.
  2. It can grow worse, as body resistance falls and current rises.
  3. It becomes milder, because the tight grip lowers the voltage.
  4. It stops, because the muscle lock blocks all of the current for good.
Show answer

Correct answer: It can grow worse, as body resistance falls and current rises.

A tighter grip lowers body resistance. With the same voltage, the current rises.
