Aluminium is _.
Correct answer: A. An excellent conductor
- A. An excellent conductor
- B. A semiconductor
- C. An insulator
- D. A photoconductor
Explanation
Option A is correct because aluminum is metal and has free electrons. As metals are conductors so aluminum is a metal and thus an excellent conductor of electricity

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.
