(b) Two wires A and B are made of copper. The wire A is long and thin, while the wire B is short and thick. Which will have more specific resistance?

Answer 1

(a) The specific resistance or resistivity depends upon

• Temperature of the conductor
• Nature of material of the conductor

(b) Both of them have the same specific resistance as they both are made up of copper.
