Materials that do not allow electric current to pass through them are called ____.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is 2 i.e. insulators
Insulators are substances that do not let the flow of electric current through them. Because of their high electrical resistance, insulators stop electrons from moving freely. Wood, plastic, rubber, and glass are typical examples. These substances are employed in electrical systems to guarantee efficiency and safety by shielding humans from electric shocks and isolating electrical conductors.
