Which statement describes the movement of electrons relative to conventional current?

• A. Electrons move in the same direction as conventional current
• B. Electrons do not move
• C. Electrons move in the opposite direction to conventional current
• D. Current direction is unrelated to electron movement

Answer: (C)

The movement of charge defines the direction we call current, and that direction is defined as the way positive charges would move. In metal wires the charge carriers are electrons, which are negative, so they travel opposite to that defined current direction. For a battery-powered circuit, conventional current is shown flowing from the battery’s positive terminal through the circuit to the negative terminal, while the electrons are pushed out of the negative terminal and move through the wire toward the positive terminal. So the actual electron flow is opposite to the conventional current direction. In other contexts, like electrolytes, current arises from moving ions, but the convention about the direction remains the same.
