No current flows between two charged bodies connected together when they have the same
- ACapacitance or $\frac{Q}{V}$ ratio
- BCharge
- CResistance
- ✓Potential or $\frac{Q}{C}$ ratio
✓
Answer
Correct option: D.
Potential or $\frac{Q}{C}$ ratio
d
There is no current flows between two charged bodies connected together when they have the same potential. For the flow of current between two conductors is that there must be a potential difference. Only then the electrons can flow from a higher potential to a lower potential.
