In the direction indicated by an electric field line:
Correct answer: B. The potential must decrease
- A. The potential must increase
- B. The potential must decrease
- C. The electric field strength must increase
- D. The electric field strength must decrease
Explanation
E is directed from higher to lower levels of V (from higher potential to lower potential).

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.
