What does it mean when a voltage source is shorted?
A circuit is said to have a short when a path in the circuit is formed that has far less resistance to the flow of current than any of the pre-existing paths between the same points. A short is often called a short circuit, even if the short constitutes only a small part of the overall circuit.
What happens if you short circuit a current source?
The voltage across an ideal current source is completely determined by the circuit it is connected to. When connected to a short circuit, there is zero voltage and thus zero power delivered.
Can dependent sources be shorted?
So for applying the theorem we have to open the current source and short the voltage source. All the Voltage & Current Sources must be Independent , otherwise if there is any dependent source you cannot Short or Open that Dependent source then you have to go with Ratio method or Test Voltage Method .
Is it a conceptual error to short a voltage source?
Figure 3 – Conceptual error of shorting a voltage source. Although shorting a voltage source is a conceptual error, there is nothing that prevents us from putting a conductive wire between the two terminals of a battery, which is what we typically call a short circuit.
Can a short circuit short a voltage source?
If we could short a voltage source, it would mean that there was a voltage difference of x volts between A and B (because of the voltage source), and simultaneously that A and B would be at the same voltage level (because of the short circuit), which is impossible!

What causes convergence issues in a Multisim simulation?
Direct voltage source across P-N junctions; this usually happens with LEDs and indicator components. Parallel voltage sources and inductors. If you are still getting convergence issues after checking for the above, your next step is to adjust tolerances. You can change the tolerances by doing the following:
Why do I get error messages when I Run simulation?
Error messages indicate that simulation results could not be generated, so they must be corrected before you will be able to analyze the circuit. When you run a simulation, the first thing that happens is the circuit is analyzed and a SPICE netlist is generated.
