In a metallic conductor, electric current is thought to be due to the movement of
- A. ions
- B. amperes
- C. electrons
- D. protons
Step-by-step solution
In metallic conductors, electric current is caused by the drift of free electrons under an electric field. Ions are not mobile in metals; amperes are units of current; protons are bound in nuclei.
