The motion of free electrons inside the metallic conductors is
Correct answer: C. Random motion
- A. Circular motion
- B. Linear motion
- C. Random motion
- D. None of above
Explanation
Free electrons inside metallic conductors move randomly (option C) due to collisions with atoms and other electrons, rather than following a circular or linear path (options A and B). Therefore, option C is the correct choice.

About Current Electricity
Steady current relates charge flow to potential difference, resistance and resistivity, including how temperature changes a conductor's resistance. Sources with internal resistance have terminal voltage below their emf when delivering current, and maximum power output occurs under a specific load condition rather than at zero resistance.
