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.

Voltage is nothing but it is pressure. Pressure is only exist in closed circuit and so it influence electron and produce current.

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

Open ckt no current flow.
Closed ckt current will be flow.
Closed ckt current will be flow.

Electron and hole only recombine if circuit are closed, this condition important for flow current.

From Ohm's law,
Current(I)=Voltage(V)/Resistance(R)
So, current is inversely proportional to resistance. Lower the resistence & the current will increase, if voltage is constant. This can happen only in case D.

Current flows in closed circuits only. At open terminals voltage is infinity that is maximum, where as current will be zero. In case short circuits, voltage is zero and current will be maximum.
So, voltage is inlfuence the current in closed circuits only.
