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

Open circuit = no current flow.
Closed circuit = current flow.
Closed circuit = current flow.

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.
So, voltage is inlfuence the current in closed circuits only.

General:
open circuit = no current flow.
Closed circuit = current flow.
It would be differ under logic gate condition.

Electrons cannot reach the positive pole without completion circuit and hence no current flow.

If circuit is not closed their will be no flow of electrons and hence no current.

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