The table shows the relative electrical conductivity of different metals. Electrical conductivity is the ability of a material to allow electric current to flow through it. The metal with the highest electrical conductivity is most suitable for use in electrical wiring because:

• Reduced Energy Loss: Higher conductivity means less resistance to the flow of electrons. This results in less energy being lost as heat during the transmission of electricity. This is important for efficiency and reducing power consumption.
• Efficient Power Transmission: Lower resistance allows for more efficient transmission of electrical power over long distances.
• Reduced Heat Generation: Less energy loss as heat translates to lower operating temperatures of the wires, improving safety and extending the lifespan of the wiring.

While other factors like cost and ductility are also important considerations in selecting a wiring material, electrical conductivity is the primary factor determining suitability.
