It isn't. If you're using superposition, you open circuit current sources and short voltage sources; this is because the current source declares the current that will be flowing through that branch.
Both current and voltage sources have a finite internal resistance.

What happens when resistors are interconnected in a circuit?
The net resistance can be found out using the algebraic sums f series and parallel connections. When there is no current flowing in the circuit the net resistance is infinite.
What are the approximations of open circuit and short circuit tests?
Firstly turn of the power before this test...Using a resistance or continuity tester you should get the following results:Short circuit: Very low resistance (nearly 0 ohms) or the bell will ring.Open circuit: Very high resistance (Somewhere in the range of Mega ohms) or the bell will not ring.The reason for this is because and open circuit has a gap in it (which has high resistance).The short circuit has wires that are crossed and so has a really low resistance.
Does an open circuit have a break that interrupts the flow of electrical charges?
Of course it has a break . open circuit means infinite resistance , so no electrical charge can flow through it .
Does the current generates if there is no resistance in the circuit?
You can have current without resistance. You would just have zero voltage drop across that zero resistance.However, the question is very interesting, because if you really had zero resistance in the entire circuit, it would be impossible to have any voltage at all without generating an infinite current, so the answer in the theoretical case is no, you can have no current, nor voltage, if there is no resistance at any point in the circuit.
How do you find shorts and opens in an electrical circuit in multimeter?
An open circuit essentially has an infinite resistance. It is shown on digital multimeter as OL. (Open Line) A short circuit should read zero, or nearly zero, depending on the accuracy of the meter.
An open circuit has an infinate resistance?
There is no such a thing as infinite resistance but it could be a very high resistance.
Infinite resistance in one direction of Diode?
After isolating the diode from the circuit, the diode shows infinite resistance in one direction and low resistance in the other direction. The diode
What is the equivalent resistance of the parallel circuit you have connected?
In principle, it is infinite. I have not connected a parallel circuit in ages.
When does a capacitor act as a resistor of infinite resistance?
When the frequency is zero(i.e when dc power is supplied), capacitor is open is treated as open circuit having infinite resistance.
What is the resistance when switch is open?
Nothing will happen to the resistance of the circuit. However, with the switch open, it will be 'seen' as having infinite resistance from the supply side.
If you cut a wire what happend to resistance?
If you are talking about the total resistance in a circuit , it depends on the components in the circuit and the location of the cut.If you are talking about a single wire, the resistance becomes infinite (or close to it) when the wire is cut.
Why is there no flow of electric current?
There are two possible causes: 1. The circuit has no Voltage applied to it. 2. The resistance of the circuit is INFINITE.
What happens when resistors are interconnected in a circuit?
The net resistance can be found out using the algebraic sums f series and parallel connections. When there is no current flowing in the circuit the net resistance is infinite.
Does an Ohmeter that has an infinite reading indicates an open circuit?
Yes, or a circuit with a resistance higher than the capability of the meter, which would be unusual.
Why does an open circuit does not make its elements function?
an opened circuit is considered to be possessed with an infinite resistance which totally opposes the flow of current in the circuit and ultimately makes the functioning of elements in the electric circuit subtle
What is the resistance if the current is 0?
If you measure zero current, then there are two possibilities,and there's no way you can tell which one is true withoutanother measurement.-- The voltage across the circuit may be zero,and the resistance could be anything.-- The resistance of the circuit may be infinite,and the voltage could be anything.
Does an open circuit have a break that interrupts the flow of electrical charges?
Of course it has a break . open circuit means infinite resistance , so no electrical charge can flow through it .
