If there is no voltage were will current flow through I mean charges flow through.

The flow of electrons is called current then where are the proton?

In case flow of current (It mean flow of electron and hole in a circuit, electron and hole are cancel each other and also current flowing will stop like (P-N junction depletion layer) then how flow current in a circuit?

In an open circuit flow of current is not possible to shorting the current or measuring the current a shunt (provide the current for further circuit) is used between positive and negative terminal.

By ohms law current is flow only closed path.

Circuit is closed the current is passing through each branch and voltage drop in the each branch.
If circuit is open no current flowing through the branch therefor their is no voltage drop.
If circuit is open no current flowing through the branch therefor their is no voltage drop.

If we have not a close circuit we have not I and V.

Circuit is closed then current passed. Circuit is open then no current passed.

This is because, only when the circuit is closed the voltage (V) is present which means the circuit is not short circuited.
If voltage (V) is present obviously current (I) will exist by the OHM'S LAW.
i.e V = IR.
If voltage (V) is present obviously current (I) will exist by the OHM'S LAW.
i.e V = IR.
