What is the body's response to a current of 5-15 mA?

When a person is exposed to an electrical current in the range of 5-15 mA, the typical response from the body includes pain and involuntary muscle contraction. At this level of current, a person will usually begin to feel discomfort, which manifests as pain. The muscular response occurs because the current can stimulate the nerves that control muscle contractions, often leading to involuntary movements.

This physiological reaction is significant because it falls within a threshold where individuals may experience effects that can be troublesome or dangerous, such as being unable to let go of the electrical source. The sensation can vary based on individual factors, but this range generally leads to these specific responses and highlights the potential risks associated with electric shock.

In contrast, other responses mentioned in the options occur at different current levels. Tingling sensations typically relate to lower currents under 5 mA, while more severe effects like heart clamps or severe tissue damage usually occur at higher current levels beyond this range.
