Q. The best conductor of electricity is:
Solution:
- Silver is the best conductor of electricity because it contains a higher number of movable atoms (free electrons).
- For a material to be a good conductor, the electricity passed through it must be able to move the electrons.
- The more free electrons in a metal, the greater its conductivity.
- Although silver is the best conductor, copper and gold are used more often in electrical applications because copper is less expensive and gold has a much higher corrosion resistance.
