What can happen if you step into a ring of different voltages?

Explanation:
When two points are at different voltages, a potential difference exists that can drive current if a conductive path connects them. If you step into a ring where those voltages differ, your body can become that path, letting electricity flow from the higher-voltage point to the lower one. The amount of current depends on the voltage difference and your body's resistance (I = V/R). Even a modest difference can produce enough current to cause a painful shock, burns, or more serious injuries, especially if there’s a path to ground or through the heart. The ring doesn’t neutralize voltage, and current doesn’t simply harmlessly surge to ground without a complete circuit. The key takeaway is to avoid stepping into areas with differing voltages and ensure circuits are de-energized before approaching.
