Electrical resistance depends on the material and cross-sectional area of the wire. Thicker wires have a larger cross-sectional area and therefore less resistance compared to thinner wires, but the length of the wire also plays an important role. In this case, since both wires have the same length, the thin copper wire will have greater resistance because it has less cross-sectional area compared to the thick copper wire.
