What is a common application of insulating materials in electrical systems?

Insulating materials are primarily used in electrical systems to prevent electric shock, which is a critical safety function. These materials are designed to resist the flow of electricity, creating a barrier between conductive parts and ensuring that electricity only flows where it is intended. This function is vital for protecting both people and equipment from the dangers of unintended electrical contact with live wires or components.

For example, wires are coated with insulating materials to prevent accidental touching and to keep current contained within the conductor, reducing the risk of shock or short circuits that could lead to more serious accidents. The design and implementation of these insulating materials are governed by safety standards to ensure they perform effectively in various conditions.

While conductivity, weight, and mechanical strength are important considerations in electrical applications, they do not directly pertain to the primary function of insulation, which is fundamentally about safety and preventing the unwanted flow of electricity.
