Question

what is the conductivity in a circuit when sulphur, carbon, copper and aluminium is used as the connecting wires

Answer 1

Explanation:

Copper have greater conductivity than aluminium, but copper is not much in use in wire due to costlier in nature, as well as heavy.

whereas aluminium is light weight and economical so, it is used in low quality products .

Graphite have smaller conductivity than copper, and aluminium it's is mainly used in batteries for smaller current.

Sulphur is pooorest conductor of electricity..
