Which of the following correctly describes an electric current?
i.Spontaneous flow of protons in gold,silver,copper,or aluminum wires
ii.Exchange of protons between cations in a solution

iv.The movement of negatively charged electrons in a metal

Question

Quizplus · Accepted Answer

Electric current is correctly described as the movement of ions in a solution (iii) and the movement of negatively charged electrons in a metal (iv). Protons do not spontaneously flow in metals, and the exchange of protons between cations does not define electric current.
