a.
To explain: The reason for considering metals as good conductors.
a.
Explanation of Solution
Introduction: Materials can be divided into good conductors and Insulators. Good conductors are those, through which electricity can pass, Insulators are those , through which
Metals are good conductor of electricity because; metals have a large number of free electrons to
b.
To explain: The reason for considering materials such as rubber, glass as good insulators.
b.
Explanation of Solution
Introduction: Materials can be divided into good conductors and Insulators. Good conductors are those, through which electricity can pass, Insulators are those, through which electric current can not pass.
Materials such as rubber, glass are good insulators because they don’t have free electrons to conduct electricity. As there is no free electrons, so flow of electric charge is not possible.
