In this experiment, around 18,000 volts are applied near an apple, and the electricity jumps through the air instead of touching the wire directly. Air normally acts as an insulator, but at very high voltages, the electric field becomes strong enough to break down air molecules, turning air into a conductive path. This phenomenon is called electrical arcing. Once the arc forms, current rushes into t

1. Electrical Isolation: The primary function of the insulator is to provide electrical isolation between the high-voltage conductor (the wire) and the supporting structures, like towers or poles. It prevents current from flowing from the conductor to the tower or ground, which could cause dangerous short circuits or power failures. 2. Material: These insulators are usually made from materials like porcelain, glass, or composite polymers. These materials have high dielectric strength, meaning th
