Discussion Overview

The discussion revolves around the behavior of charge flow when two conductors with the same charge are connected. Participants explore the relationship between charge, potential, and capacitance, questioning the conditions under which charge may or may not flow between the conductors.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant asserts that no charge will flow between two conductors with the same charge, but questions whether this statement is always true, suggesting that potential differences may allow for charge flow.
  • Another participant introduces the relationship between charge, capacitance, and potential, indicating that capacitance is relevant to understanding charge flow.
  • A participant expresses confusion about the connection between capacitance and charge flow, seeking clarification.
  • It is proposed that if two charged conductors have the same potential, then charge will not flow, as the potential difference is necessary for charge movement.
  • One participant notes that a small sphere will have a lower potential than a larger sphere if both have the same charge, suggesting that this difference could lead to current flow when connected.

Areas of Agreement / Disagreement

Participants express differing views on whether charge will flow when two conductors with the same charge are connected. Some agree that potential differences are crucial for charge flow, while others highlight scenarios where charge may still move despite similar charges.

Contextual Notes

Participants discuss the implications of capacitance and potential differences, but the discussion includes unresolved assumptions about the conditions under which charge flow occurs, particularly regarding the geometry and shape of the conductors.

Who May Find This Useful

This discussion may be of interest to those studying electrostatics, charge interactions, and the principles of capacitance in conductive materials.

Can anybody pleasez answer my question...?

--->>No charge will flow when two conductors having the same charge are connected to each other. IS this statement true or FALSE?...

what i think is ..it is not necessary that the potential of both conductors is also same..

So due to potential difference there can be a charge flow..

Hence, the statement is not always true...

One more question ..When the above statement is TRUE?...

last question...

If two charged conductors having same potential are connected..will there be a charge flow..?
 
Physics news on Phys.org
Hint: Q = C*V

Q = charge, C = capacitance, V = voltage/potential
 
@PhysTech : I didnt understand wat u have written...
does capacitance has a connection with this?
 
D_DaYwAlKeR said:

That is the connection to capacity: It is the relation between potential difference and charge.

So due to potential difference there can be a charge flow..

Hence, the statement is not always true...
Right.

If two charged conductors having same potential are connected..will there be a charge flow..?
What do you think? ;)
 
@mfb ..

now i understood the connection of capacitance...
so it means that if two bodies having same charge and same capacitance have same potential...
and if they have same charge and same shape and geometry they will have same potential...

i think if the potentials of two bodies are equal..then charges will not flow as the difference in potential is the driving force which, in this case is absent..

Am i correct?
 
That is right.
 
A small sphere will have a lower (magnitude of) potential than a large sphere if they both have the same charge on them. Hence, a current will flow when they are connected.
That's the first level of description of what goes on. It gets better / worse, though.
