State whether the following is TRUE or FALSE: No charge will flow when two conductors having the same charge are connected to each other.
Solution
The electric potential is the driving force for the charges to flow and a current flow to be established in a circuit. Conductors with equal charge may possess different potential at their respective ends. In a closed circuit the total charge flow remains a constant.
Complete answer:
We have learned in current electricity that current is the effect of the acting electric potential on a conductor. Here, the electric potential acts as an equivalent of force in electric current, whereas the current flowing is the effect caused by this potential difference.
The potential difference is the difference in the electric potential between two points of a conductor. It is this difference in potential that drives the electron from one end to the other end in a metal conductor. The number of electrons or charge in the system always remains constant.
This is the same explanation for two conductors connected together. The flow of charges can take place only when there exists a potential difference between the two conductors. Otherwise, both the conductors are in equilibrium and don't constitute any flow of charges.
Therefore, the statement as per the question does not hold good without a potential difference between the conductors.
So, the statement is FALSE.
Additional Information:
A higher potential body when touching the ground can constitute a flow of charges which is known as earthing.
Note:
In electrostatics, the charges at rest develop an electric field which can attract or repel the charges around them. This can result in a sudden jump of charged particles from its position to attain equilibrium. In current electricity, the flow of charges is due to the potential difference only.
