When circuit will be close, only in this condition electrons shall flow. Because for the current two poles must have (positive pole and negative pole.

But what about in the transformers?

To flow the current the electron-hole pairs should be recombined that is done when only the circuit is closed.

Resistance is more if thre is an open path and current can't reach the desired destination so if it is cloesd then we can say the volt influence the current to move only if the circuit is closed.

Open circuit has infinite resistance and we know that resistance is opposition to flow of current if opposition to current is infinite then current is zero so we have ohms law
(i.e) v/i=r if i=o then v=o.
So circuit must be closed.
(i.e) v/i=r if i=o then v=o.
So circuit must be closed.

We know that current always flows through low resistance path. During the open-circuit condition the circuit has high resisance.

I agree with ruchi.

v=ir, in open ckt i=0, then v also 0,

Current will flow through minimum resistance path only. In a open circuit n/w resistance offered is very high so current will be zero.

Open circuit=no flow current.
If voltage sourse is present & curcuit is open then current will not flow.
If voltage sourse is present & curcuit is open then current will not flow.
