The correct Answer is:
To determine when charge flows between two conductors connected by a wire, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding Conductors and Charge Flow**: - Two conductors can hold electric charge. When they are connected by a wire, they can exchange charge. 2. **Potential Difference**: - For charge to flow from one conductor to another, there must be a potential difference (voltage) between them. This means that one conductor must have a higher electric potential than the other. 3. **Ohm's Law**: - According to Ohm's Law, the current (I) flowing through a conductor is directly proportional to the potential difference (V) across it, given by the formula: \[ I = \frac{V}{R} \] - Here, R is the resistance of the wire. If the potential difference (V) is zero, then the current (I) will also be zero, meaning no charge will flow. 4. **Condition for Charge Flow**: - Therefore, charge will flow between the two conductors if: - There is a non-zero potential difference between them (i.e., \( V \neq 0 \)). - The conductors are connected by a conductive path (like a wire). 5. **Conclusion**: - In summary, charge flows between two conductors connected by a wire only when there is a potential difference between them.

Consider two conductors. One of them has a capacity of 2 units and the capacity of the other is unknown. They are charged until their potential are 4 and 5 units respectively.
