What is one of the primary functions of electrical insulation?

The primary function of electrical insulation is to contain the voltage. This means that insulation acts as a barrier to prevent electrical current from escaping the conductor and reaching unintended areas or components. By effectively containing the voltage, insulation protects both the electrical circuit and individuals from electric shock, short circuits, and potential fires.

Electrical insulation also serves to reduce the risk of interference in nearby circuits and ensures the efficiency of the system by minimizing losses due to leakage currents. Materials used for insulation are typically non-conductive, providing a secure environment for electrical conductors to function safely.

Other options, while they may suggest certain qualities or benefits associated with the construction of electrical systems, do not inherently address the primary role of insulation.
