Final answer:
To minimize the risk of electric shock when working with high-power electric circuits, it is advised to work "one-handed" or "keep one hand in your pocket." This prevents the completion of a circuit and reduces the likelihood of experiencing a shock.
Step-by-step explanation:
When working with high-power electric circuits, it is advised to work "one-handed" or "keep one hand in your pocket." This suggestion is sensible because it reduces the risk of electric shock. If you were to touch a live wire with both hands, the electricity would pass through your body, potentially causing harm. By keeping one hand away, you minimize the chance of completing a circuit and experiencing a shock.
