General Science (Easy) Physics

Two pieces of metallic wire having equal lengths and equal volume placed in air have different resistances. The two wires must

have different cross-sections

have different temperatures

be of different materials

be of same density

be of different materials

- If the two wire are of same equal lengths and equal volume placed in air have different resistances. it can lead to short circuit.
