No electric current will flow between two charged bodies if they have same:
- Potential
- Charge
- Capacity
- None of these
Correct answer: 1. Potential
Explanation: Electric current flows from a region of higher electric potential to a region of lower electric potential. In other words, it flows from a point of higher electric potential energy to a point of lower electric potential energy.

If two charged bodies have the same potential, it means they are at the same electric potential level. In this case, there is no potential difference between them, and as a result, no electric current will flow between them. Electric current requires a potential difference to drive the flow of charged particles (usually electrons).

So, the absence of a potential difference (having the same potential) is the condition under which no electric current will flow between two charged bodies.
