Answer :
The silver wire will be longer than the copper wire as the silver has the high expandability than the copper and not just that the silver is very good conductor for electricity but we use copper for wires cause of there cheap availability.
what is resistance?
The amount that an object impedes or resists in an electric current is referred to as resistance. Electric current is the flow of electrons. Consider an example of a person attempting to move from one shop to another in a busy market. This condition is eerily similar to an electron attempting to pass through a wire.
Resistance is the property of materials that allows electric current to flow. Resistance unquestionably resists the passage of current. Furthermore, the unit of resistance is ohms, which is symbolised by the Greek capital letter omega. Furthermore, resistance is affected by the voltage across a resistor as well as the current running through it. Resistance is a measure of the resistance to current flow in an electrical circuit.
