An uncharged conductor has?
Correct answer: D. All of these options are correct
- A. Electrons
- B. Protons
- C. Holes
- D. All of these options are correct
Explanation
An uncharged conductor is electrically neutral, meaning it has an equal number of protons and electrons. Electrons are free to move within the conductor, allowing it to conduct electricity, but this movement does not change the overall charge balance unless acted upon by an external electric field. Protons remain fixed within the atomic nuclei and do not move freely. In the context of conductors, 'holes' are not typically considered, as they are more relevant to semiconductor physics. Therefore, the correct choice is that an uncharged conductor has all these components, maintaining an overall neutral charge.

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.
