A $10$ $mm$ diameter electrical conductor is covered by an insulation of $2\:mm$ thickness. The conductivity of the insulation is $0.08$ $W/m-K$ and the convection coefficient at the insulation surface is $10$ $W/m^2-K$. Addition of further insulation of the same material will

  1. increase heat loss continuously
  2. decrease heat loss continuously
  3. increase heat loss to a maximum and then decrease heat loss
  4. decrease heat loss to a minimum and then increase heat loss
