- Metal is an electrical conductor
- Metals usually have higher conductivity than nonmetals
- Hence, metal is the material that has a higher conductivity than other materials

- Metal is the material that has a higher conductivity than other materials
- Metal fork is made of metal
- So, metal fork is the best conductor of electricity in this example
