At what milliamp level does a person feel a shock but may not experience pain?

A person typically begins to feel a shock at a milliamp level between 1 milliamp and 5 milliamps. At around 1 milliamp, a slight sensation is felt, which may not necessarily be painful. The threshold at which a person experiences pain generally starts closer to the range of 5 to 10 milliamps, but there can be variability among individuals.

The selection of 5,000 milliamps is significantly higher than the levels at which one usually starts to feel a shock. At this level, the electric current can cause severe injuries or be fatal, rather than just being a sensation without pain. The other options of 10,000 and 15,000 milliamps would likely result in serious electrical injuries or death. Therefore, choosing 5,000 milliamps as the point of feeling a shock without pain aligns with the understanding of human sensitivity to electric current.
