What is the primary function of insulation in electrical systems?

The primary function of insulation in electrical systems is to prevent current leakage. Insulation provides a barrier that keeps electrical currents confined to their designated paths, such as within wires or components. This is crucial for ensuring safety and efficiency in electrical systems because leakage can lead to short circuits, equipment damage, and increased risks of electrical shock.

Insulation materials, which are typically non-conductive, help maintain the integrity of electrical systems by minimizing unintended conduction, thus protecting both the system and users from hazards. The effectiveness of insulation contributes to the overall stability and reliability of electrical networks by ensuring that electrical currents do not escape their intended routes.
