Question

la wire two wires A and B are of equal length different cross section area and made of same metal
A) name the property which is same for both wire and justify your answer
B) name the property which is different for both wire ​

Answer 1

(A) the ans is resistivity

• as resitivity doesnot depend on length and thickness
• it depends on nature of material as the both the wires are made of same metal thats why they will have same resitivity

(B) the property which will be different is resistance

• as resistance depends on LANT(length,area,nature of material, and temperature)
• both the wires have different cross section area so they will have different resistance
• cross section area is inversly proportional to resistance
