An electric material must be:
Correct answer: B. Good conductor
- A. Resistor
- B. Good conductor
- C. Insulator
- D. Semi-Conductor
Explanation
So electric material can be good conductor. A good conductor is a material that allows electric current to flow through it easily. Metals such as copper and aluminum are examples of good conductors

About Electrostatics
Electrostatics describes forces between charges through Coulomb's law, electric fields and field intensity, then uses electric potential to measure energy per unit charge. Capacitors store charge and electrical energy, with capacitance depending on geometry and dielectric material, not simply on the amount of charge present.
