What is an electric current in a metal wire?

AMoving protons
BMoving neutrons
CMoving electrons
DMoving molecules
Answer & Solution
Correct answer: C. Moving electrons
1. In a metal the electrons are free to move rather than being tied to one atom. 2. A cell in a complete circuit pushes all of them in the same general direction. 3. That movement of electrons through the conductor is the electric current. 4. Protons and neutrons stay locked in the nucleus and do not travel. _Source: Siyavula Natural Sciences Grade 8 (CC BY 4.0), What is an electric current?_
