Solution

(a) Copper or Aluminium is used as a material for making connection wires because the resistivity of these materials is very small, and thus, wires made of these materials possess negligible resistance.

(b) The connection wires are made thick so that resistance can be considered as negligible. This is because resistance is inversely proportional to cross-sectional area.
