Because it is a nonmetal
Abrasion resistance is low.
The electrical resistance of a penny can vary based on its composition and condition, but a typical copper penny (post-1982) has a resistance of about 1 to 2 ohms. This value can change due to factors like oxidation, surface condition, and temperature. Generally, the resistance is low due to copper's excellent conductivity.
Earth resistance, or ground resistance, ideally should be as low as possible to ensure effective grounding for electrical systems. Typically, a resistance value of 1 ohm or less is recommended for most applications, especially in electrical installations, to minimize the risk of electrical shock and improve system performance. However, acceptable values can vary depending on local regulations and the specific requirements of the electrical system. Regular testing and maintenance are crucial to ensure that earth resistance remains within safe limits.
Low resistance. Think of Ohm's law. Voltage drop is directly proportional to resistance. The higher the resistance, the higher the voltage drop, and the less voltage that is available for the load. Think of conductor resistance as a resistance in series with the load. Also, higher conductor resistance means more power lost, going to heating the conductors. The "line loss" formula is P=I2R. The greater the resistance, the greater the electrical power being converted into thermal power heating the conductors.
Voltage(E)=Amps(I) x Resistance(R) (ohms) use this formula to solve for other two.

Abrasion resistance is low.
A material that loses its resistance to electrical flow at very low temperatures is called a superconductor. This phenomenon is known as superconductivity, where the material exhibits zero electrical resistance below a critical temperature.
Copper is known for its low electrical resistance, making it a highly conductive material. This property of copper makes it ideal for use in electrical wiring and other applications where efficient electrical conductivity is required.

Gold has a low resistance, which means it is a good conductor of electricity. This property makes it useful in various electrical applications where low resistance is needed for efficient conduction of electricity.
Silver and gold both have low resistances. Superconductors have zero electrical resistance. People with acquired immune deficiency syndrome (AIDS) also have low resistance to infection. Many women have a low resistance to my charming and magnetic personality.
super conductor
Yes, low resistance can enhance conduction speed by allowing the electrical signal to travel more easily through the material. This is important in various contexts, such as in electrical circuits or in nerve fibers in the human body, where low resistance leads to faster transmission of signals.
