Will current flow more easily through a thick wire or a thin wire of the same material, when connected to the same source? Why?

Current is the rate of flow of charges. It will flow easily through the thick wire.

Why current will flow easily through the thick wire?

According to Ohm’s law, the resistance of a wire is inversely proportional to its cross-sectional area.

  • The thick wire will have a larger diameter than the thin wire, therefore, its cross-sectional area will be larger than the thin wire.
  • Therefore the resistance of the thick wire will be less than that of the thin wire.
  • The lesser the resistance, the more easily the current will pass through it.
