Question
Which of the following statement/s is/are correct about electric current:Statement 1 : It is the rate of flow of electrons.Statement 2 : It is the rate of flow of protons.
Solution
Statement 1 is correct. Electric current is indeed the rate of flow of electrons. Electrons carry a negative charge and when they move, they create an electric current.
Statement 2 is incorrect. In most cases, electric current is not the rate of flow of protons. Protons are located in the nucleus of an atom and do not move around freely. The movement of protons does not typically contribute to the flow of electric current. However, in some cases like in plasma or ionic solutions, positive ions (which could be protons) do move and carry current. But in the context of electric circuits which we usually refer to, it's the electrons that move and create current.
