Answer to Question #158892 in Electric Circuits for Kabera Arnaud

Question

Compared to the number of free electrons in a conductor, the number of free electrons in an insulator of the same volume is less, greater or same

Answer 1

Materials with high electron mobility (many free electrons) are called conductors, while materials with low electron mobility(few or no free electrons) are called insulators. So compared to the number of free electrons in a conductor, the number of free electrons in an insulator of the same value is less.
