When a random electron strikes a neutral conductor, it does not necessarily increase the conductor's voltage significantly due to the conductor's ability to dissipate excess charge. Conductors are typically connected to other conductive materials or grounded, allowing any net charge from electron strikes to flow away. The frequent occurrence of charged particles, such as cosmic rays, does not lead to dangerous voltage buildup because the charge can escape through various mediums. Even isolated conductors are not truly isolated, as they interact with surrounding air and moisture. Therefore, the risk of electrocution from such events is minimal.
