What is Short Circuit Current?
I fp is the first peak short circuit current. It is the maximum instantaneous value of the current that will reach during the first moment of a short circuit current. I pc is the rms value of the periodic component of the short-circuited current. During the steady state, the rms value of the short-circuit current remains almost constant.

If short circuited, it doesn''t means two nodes. It will be single node only. As per @RedGrittyBrick image shown, both (node1 and 2) will be representing single node only. And potential difference is measured across two nodes. So if you connect battery or DC source in your case, current will flow from high potential to low potential.

capacitance
You can think of shorting a charged capacitor like you would shorting a battery. When you short a storage device the only resistance in the circuit is the tiny resistance of the wire and the ESR (Equivalent Series Resistance) of the device itself. Assuming a perfect short, the current would be limited only by the ESR which tends to be very low ...
Voltage in a Short Circuit
The time it takes to reach the 0 volt state depends on the maximum discharge current of the battery. In theory, if you short circuit a voltage source the current would be infinite to maintain the same supply voltage. That is not possible in practice. When an actual power supply or a battery is shorted, very high current flows for very short ...
Ground Fault vs Short Circuit: Understanding the Key Differences
Short Circuit: A short circuit happens when a live (hot) wire directly contacts a neutral or another live wire. This creates a new, shorter path for electricity to flow, bypassing the rest of the circuit. This can occur due to faulty installation, damaged wires, or when insulation wears off, allowing wires to touch. Causes and Common Scenarios. Ground Fault Causes: Wet conditions, …
What exactly is a short circuit?
A short circuit may be in a direct- or alternating-current (DC or AC) circuit. If it is a battery that is shorted, the battery will be discharged very quickly and will heat up due to the high current flow.

High Current or High Voltage that damages components?
$begingroup$ Thanks @Wes, this is what I was looking for. To confirm, in a simple working circuit with various components, and I doubled the voltage, but also doubled the resistance so the current remained the same, this can cause damage? ..and vice versa, if I halved the resistance but kept the source voltage the same, this will double the current and …
Closed, Open, and Short Circuits
With nothing in the circuit to limit the current and absorb the electrical energy, heat builds up quickly in the wire and in the power supply. A short circuit can melt the insulation around a wire and may cause a fire, an explosion, or a release of harmful chemicals from certain power supplies, such as a rechargeable battery or a car battery.
voltage
A short is a current path with no resistance. All that is determined by what you are measuring across. The reason why you can read current and voltage across a battery is because batteries have internal resistance. Battery by itself is open. When you put your leads on battery, you complete or close the circuit. Shorts bypass the load straight ...

Short Circuit
When a short-circuit occurs, the current in the system increases to an abnormally high value while the system voltage decreases to a low value. The heavy current due to short-circuit causes excessive heating which may result in fire or explosion. Sometimes short-circuit takes the form of an arc and causes considerable damage to the system.
