Maybe there's no voltage-source(AC or DC) because voltage is the one that motivates electrons to flow. It could be the connection of components in your circuit.
A 4000-Ω resistor is connected across 220 V will have a current flow of 0.055 A.Ohm's law: Voltage equals Current times Resistance

Resistance is the property of a component which restricts the flow of electric current.
series network consists of components i.e resisters connected end to end. since their is only one path for the flow of current. but potential drop across each resister is different. so thats the reason that series network has maximum resistence then the highest resister in combination. the same amount of current passes through each resister.
As long as an electrical power source is connected to itself with electrical conductors of some kind, then a current will flow through it. How much current will depend on the components used in the circuit.

how does electric current flow in the b connection? do the two bulbs in a series circuit, light when the middle bulb is loose? why?
Switches either allow the current to flow or turn it off
In a parallel circuit, the current flow is independent in each branch.
Consider the electric current to be like the flow of water. In a series circuit, the downstream wire of the first device is connected to the upstream wire of the second device. So the current has to flow through device one, then device two. In this case, total resistance is increased because it is harder for the current to flow through two devices. In a parallel circuit, the upstream wires of the two devices are connected to each other, and the downstream wires of the two devices are connected. So, part of the current will flow through device one, and the rest of the current will flow through device two. In this case, total resistance is decreased because the current can flow more easily through the resistors (this takes a little math to really prove, but the conclusion still holds). Some circuits can have some devices wired in series, and others in parallel, but these circuits should not be confused with simple series and parallel circuits.
The ammeter does affect the flow of current in a circuit, however, the resistance of the ammeter is so small in comparison to the circuit that the effect is negligible. It is connected in series.
a 30 pf capacitor is connected into a 240v, 60 hz circuit. what is the current flow into the circuit
A 4000-Ω resistor is connected across 220 V will have a current flow of 0.055 A.Ohm's law: Voltage equals Current times Resistance
The number of batteries has only an effect on the amount of current when they are equivalent and connected in parallel. The amount of current that can flow from a group of batteries connected in series is limited to the current provided by the battery that produces the lowest current flow in the string.
