Which technique can reduce the risk of current affecting your heart or brain when working on live circuits?

Keeping one hand in your pocket while working on live circuits is a technique that greatly reduces the risk of electrical current affecting the heart or brain. This method works because it minimizes the chance of a current passing through the chest or head, which could lead to serious injury or even death. By keeping one hand away from the circuit, the body is less likely to form a path for the electrical current to travel through vital organs.

This technique is part of standard safety practices when working with electrical systems, as it helps to ensure that even if one hand inadvertently comes into contact with a live conductor, the other hand remains isolated, limiting the overall impact of any accidental electrical shock.
