Question

39. The table shows four different materials and their resistivity. (i) Which material is the best conductor of electricity? i​

Answer 1

Explanation: THE MATERIAL WITH LEAST RESISTANCE WILL BE THE BEST CONDUCTOR OF ELECTRICITY.WE KNOW THAT

R=ROH(l)/A

=l/A is constant

hence lower the value of resistivity best will be the conductor

hence P WILL BE THE BEST CONDUCTOR.

Answer 2

Silver is the best conductor of electricity, as the metal has more free electrons to transfer electric energy.

Higher the number of free electrons more efficient the metal to conduct electricity.
