Which of the following is true of an electrical charge?
Answer Details
The correct answer is option D: "All of the above."
An electrical charge refers to the presence of an excess or deficit of electrons in an atom or molecule. In this context, positive charge means a deficit of electrons, whereas negative charge means an excess of electrons. Electric current refers to the flow of charged particles, typically electrons, through a conductor. Therefore, an electric current means the movement of electrons.
In summary, all of the given options are true of an electrical charge, and they all relate to the behavior of electrons in an electrically charged system.
