      Hi - Why does a wire with larger diameter have less resistance than wire with smaller diameter?
    • Karthik R


      This is because the resistance of the wire is inversely proportional to the cross-sectional area of the conductor. larger the diameter more the area of cross section. so more the area of cross-section lesser the resistance.

      This can be deducted from the Resistance formula: Resistance = (Resistivity*length)/Cross sectional area.
