The current that flows in a circuit, measured in amperes, is electrons that move from a point of higher potential (voltage) to a point of lower potential when a resistance is appied to the circuit. Simply put, a resistance can be any object connected to a circuit, such as a TV, computer, vacuum cleaner and so on. The inner resistance of the equipment is what causes the current to flow, as it "draws" the electrons from the supply side of the circuit to it. As long as there is voltage supplied to the object, the inherent resistance of the object will naturally draw current, causing the object to work.

If the circuit is a closed one,then current flows in that circuit.

When its closed. You close the circuit in order to complete it. Like when you turn a light switch on, you have closed the circuit . When you turn it off, your opening the circuit.
So the answer to your question would be, current flows threw a circuit the instant it's closed, and then its completed..
My answer is as lucid as one can be so if you easily understood me then you know what lucid means.

Think of it like water flowing downhill. If it's not stopped as by a dam. If it has a path to flow to a lower elevation. Current will flow if there's a path that is not infinite resistance, and you have a complete circuit.

Of course when the circuit is complete i.e. there is no break in connections made using a conducting wire and with a source to provide potential difference such as a cell.

When there is a potential difference between two points in a circuit.

When an EMF is applied to it. EMF is voltage and the circuit has to be closed.

The battery in flight is a rapid discharge, the battery is elementary to warmth. fee, see you later through fact the fee, the battery is incredibly purely somewhat micro thermal. Battery lack of ability to fly the plane rotor rotation, can not fly, could nicely be charged, to not be used is purely not diverted to recharge, I fee so there are purely flying off the battery do not on the instant fee (cooling approximately one hour and then fee remember!!)
