The flow of charges produces:
Correct answer: D. All of the above
- A. Current only
- B. Magnetic field only
- C. Electric field only
- D. All of the above
Explanation
Electric current is the rate of flow of charges. In electric circuits this charge is often carried by electrons moving through a wire.Current generally refers to the flow of charges. A stationary charge produces only electric fields whereas a moving charge produces both electric as well as magnetic fields.

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.
