The effects of 60-Hz current on a human for 1-second are shown below. By matching the current to the physiologic effect, select the correct option from the given options.

1) 1 mAmp Let Go Current
2) 15 mAmp Microshock risk
3) 100 microAmp V. Fibrillation
4) 200 mAmp Perception Threshold

Final answer:

The effects of 60-Hz electrical current on the human body depend on the current's intensity, with a perception threshold at 1 mA and the 'let go current' usually ranging from 5 to 30 mA. Risk of microshock and V. Fibrillation typically occurs at lower and higher thresholds, respectively.

Step-by-step explanation:

The question concerns the physiological effects of 60-Hz electrical current on a human when exposed for a duration of 1 second. Based on the given data and typical safety standards that are used, we can make a few conclusions about the correct pairings of current and physiological effect:

A perception threshold of 1 mA, where a person can feel the current but it is not harmful.
