Solution

Conductors conduct electrical current very easily because of their free electrons. Insulators oppose electrical current and make poor conductors. Some common conductors are copper, aluminum, gold, and silver. Some common insulators are glass, air, plastic, rubber, and wood.
Same potential difference is applied to a good conductor and a bad conductor of same dimensions. The bad conductor produces more heat.
