Answer 2

The resistance of a wire does not depend on the potential difference applied across the ends of wire. (option D)

• The formula of resistance is given by, R = ρL/A
• Where "ρ" is the resistivity, "A" is the cross-section area of the wire, and "L" is the length of the wire.
• Resistance depends on the material of wire used, area of cross-section, length of the temperature, and temperature.
• Resistance acts as an opposition to current flow, it does not depend on the potential of the wire since R is just used as a constant.
