Every Material Offers Some Resistance or Opposition to The flow Electric Current Through it, Good Conductors such as Copper and Aluminum Offer Very Little Resistance. Poor Conductors or Insulator Such as Glass, Wood and Paper Offer a High Resistance to Current Flow.
The Size and type of Materials of the Wire in an Electric Circuit are chosen to keep the electrical resistance as low as possible. In this Way, Current can flow easily through the conductors.
Temperature also affects the resistance of electrical conductors to some extent. In most conductors the resistance increases with temperature. The relative resistance of several conductors of the same length and cross section metals are arranged in order of ascending resistance.
