Physics · Electric current: drift velocity, mobility and their relation with electric current
Electric current flows through:
Electric current flows through:
- A. a conductor
- B. an insulator
- C. free space
- D. none of these
Step-by-step solution
Electric current is the flow of electric charge. Conductors have free charge carriers (e.g., electrons) that can move, allowing current flow. Insulators lack free charge carriers, and free space is devoid of charge carriers, so current does not flow through them. Thus, the correct answer is a conductor.
