The question is vague.
A current source is the short form of constant current source.
A voltage source, on the other hand, is the short form of constant voltage source.
That being so, then no, a current source is not available in any circuit.

A complete electric circuit includes a voltage source current wires and something to ground the flow of current?
If you ground the flow of current like the last part of your question states you will not have a complete circuit as the circuit will open on a short circuit. To make a complete circuit operate you need a power source, an overload device to protect the conductors of the circuit, conductors to carry the current and a load across the power source which causes the current to flow in the circuit. Leave any one of these things out and you will not have a complete circuit.
Why does not it matter where you measure the current in a simple circuit?
The current measured at any point in a simple circuit will be the same because current is the measure of electron flow through a circuit. The current flowing through any branch of any circuit (or an entire simple circuit) will always be the same at any point.
How the superposition theorem is used to find the currents in a circuit supply by more than one voltage source?
1.Put a short circuit instead of voltage source 1 and find what you want with taking direction of current in that element(ris.ind.cap.) 2.puta short circuit instead of voltage source 2 and find what you want with taking direction of current in that element(ris.ind.cap.) 3.add current 1 and 2 for any element.
When a current is stopped at any the whole circuit becomes open what current is that?
An open circuit has no current ( 0 amperes ).
What electrical quantity is the same throughout a series circuit?
In any series circuit, there is one and only one path for current flow. All the current flowing in the circuit will flow through all of the devices in that circuit. A break at any point in the circuit will cause current flow to cease. Lastly, it is current that is the same at any point in the circuit where we'd care to measure it.
What is the current source replaced by open circuit across the terminals?
because an ideal current source is assumed to produce a constant current for any voltage and is assumed to have an impedence of infinity (open circuit).
What does the term closed circuit mean relative to electricity?
Closed circuit means circuit is complete without any break in between and current is flowing if there is any source.

What is the Difference between voltage controlled device and current controlled device?
The difference between a current control device and voltage controlled device is that for current controlled device, the current is constant and the voltage is variable while for a voltage controlled device, the voltage is constant and the current is variable.
How many path ways are available for electrons to travel in a series of circuit?
A "series" circuit is one in which there exists one single current path all the way, and there's no point in the circuit where current has any choice of where to go.

What two wires touching causes a short circuit?
the red wire and the blue wire A touching of two wires coming from any potential power source will cause a short circuit Short circuit relates to the quickest path back to the source with out any resistance to the current flow.

What is the relation between surge current and fault current?
Fault/short circuit current is the available current from the source when a short circuit occurs. It is the maximum current the source can provide, defined as an RMS value, usually without any DC offset. Surge current is the maximum instantaneous current that is drawn by "turning on" or energizing a device such as a motor or transformer. Surge current will be less than fault current. If you assume a very strong source relative to the device rating, the surge current will be solely dependent upon the device in question (so fault current and surge current have no intrinsic connection). For a transformer, inrush may be 5-7 times the self cooled full load rating. Motors are usually less than this, and depending on the starting technique and configuration can be little (20-50%) over full load rating. From these definitions, and the above paragraph, it should be clear that if you have a weak source relative to the device, the device may not be able to draw as much current as it would if connected to a stronger system. If this occurs, the voltage will dip. An example would be a system where the available short circuit power is 600MVA; A 60MVA transformer is connected to this system bus. Energizing this transformer without any sort of controled closing could result in (7) x 60MVA = ~420MVA on inrush. This is relatively close to the available short circuit power (70%), so you can expect the system voltage to dip as a result. If the available short circuit current was around 20,000MVA, energizing such a transformer would not cause any significant system voltage dip.
What are the set ups for an electronic current to be completed?
To have any current flow in a circuit there must be a connected load to the power source. Without a load all you would have is a voltage potential between the supply wire and the return to the power source wire.
When a current is stopped at any the whole circuit becomes open what current is that?
An open circuit has no current ( 0 amperes ).

In any series circuit, there is one and only one path for current flow. All the current flowing in the circuit will flow through all of the devices in that circuit. A break at any point in the circuit will cause current flow to cease. Lastly, it is current that is the same at any point in the circuit where we'd care to measure it.
