A grounded tool helps ensure what regarding stray current?

A grounded tool is designed to ensure safety by redirecting any stray current that may occur to the ground. When tools are grounded, they provide a safe path for electricity to flow into the ground in the event of a fault or malfunction, such as insulation failure. This prevents the risk of electric shock by ensuring that the user does not become the path of least resistance for the current. By connecting the tool's metal parts to the ground, any excess or unintended current can safely dissipate, which is crucial in minimizing the risk of electric shock that could occur if the tool were not grounded. This grounding mechanism is essential in maintaining electrical safety standards in environments where electrical tools are used.
