Understanding Dielectrics and Insulators in Electrical Engineering

Dielectric materials, also known as insulators, have tightly bound electrons with no free charges, characterized by a forbidden energy band gap of over 4 eV. Insulators, on the other hand, prevent electric current flow due to high resistivity and strong covalent bonds. Learn about the differences, d
