What effect is associated with a current level of 17 - 99 mA?

When a current level ranges from 17 to 99 mA, it can have serious physiological effects on the human body. The correct choice highlights that this level of current can induce extreme pain, respiratory arrest, and severe muscular contractions.

At this range, the electrical current is strong enough to significantly stimulate the nervous system and muscle tissues. This stimulation can cause painful reactions and may even lead to involuntary muscle contractions. If the current passes through the chest area, it might disrupt the normal rhythm of the heart, potentially leading to respiratory arrest as the body's muscles, including those necessary for breathing, clamp down uncontrollably.

It's important to recognize that electrical currents of this magnitude pose serious risks, and understanding these risks is vital for safety practices in environments where electrical hazards are present.
