Question

two wires are made of silver and copper both are given same current for the same time in which wire more heat would be grated and why​

Answer 1

Answer:

here is ur answer

Explanation:

Electrical resistivity is an intrinsic property that quantifies how strongly a given material opposes the flow of electric current. A low resistivity indicates a material that readily allows the movement of electric charge. Resistivity is commonly represented by the Greek letter ρ (rho). The SI unit of electrical resistivity is the ohm−meter(Ω−m).

The electrical resistance of a wire would be expected to be greater for a longer wire, less for a wire of larger cross sectional area, and would be expected to depend upon the material out of which the wire is made. Hence, the resistance of a given material will increase with the length, but decrease with increasing cross-sectional area.

In this case, two wires A and B are made of copper and so there would no change due to the material of the wire. The A wire is made thin and long compared to the B wire which is short and thick.

Hence, the wire A has more resistance as the resistance of a given material will increase with the length, but decrease with increasing cross-sectional area.

Answer 2

In copper because in silver current will flow very easily as it is the best conductor so copper will heat first
