When a battery is short-circuited, the positive and negative terminals are connected directly without any resistance. This creates a pathway for a large current to flow through the battery, which can cause it to overheat, leak, or even explode. Recharging a short-circuited battery can further damage it and may even be dangerous.
With a short circuit present the resistance of the whole circuit is dominated by the internal resistance of the battery. That being so the current in the circuit is of the order of emf of battery ÷ internal resistance which can be very high if the internal resistance is very low.
This usually happens during some-or-other incident, but it can also be the result of human carelessness or malice. Short circuiting a battery deliberately, or accidentally connects the positive and negative battery nodes, forcing them to be the same voltage. The result, as Wikipedia puts it aptly, is a connection with almost no resistance.
You are stating something else. A short circuit of a battery is the formation of a low resistance path between the terminals of a battery. With a short circuit present the resistance of the whole circuit is dominated by the internal resistance of the battery.
In electronic devices, a battery internal short circuit can cause permanent damage to the device’s components, making it unusable. Preventing internal short circuits is essential for maintaining the safety and functionality of electrical systems.
Well short circuit can produce very high temperatures that’s mainly due to the fact that that a large amount of current flows through the circuit generating the heat. Let’s take a small example, if a 9v battery is shorted then the battery will be discharged very quickly and will heat up due to the large current flow.
Let’s take a small example, if a 9v battery is shorted then the battery will be discharged very quickly and will heat up due to the large current flow. Similarly, if a charged capacitor is short circuited the resulting high current flow and the huge power dissipation will cause the wire to explode.

Get PriceIf this battery resistance is 2 ohms it will still allow the battery to power a radio or a small light bulb, but if you hold a screwdriver shaft across the battery terminals, this "short circuit" current will be limited by the battery''s 2 ohms. There just won''t be a huge current through your low resistance screwdriver, in this example, so there won''t be much voltage across it.
Get PriceShort circuits can cause very high currents to flow in power supplies or in wiring that it not designed for such a load. This can result in very hot wires and creation of a fire risk. Damage to components can occur. Circuits usually have a fuse included that will ''blow'' if a ''short'' causes too much current to flow.
Get PriceVoltage is the energy per unit charge. Thus a motorcycle battery and a car battery can both have the same voltage (more precisely, the same potential difference between battery terminals), yet one stores much more energy than the other. The car battery can move more charge than the motorcycle battery, although both are 12V batteries.

Get PriceThe neutral wire completes the circuit and carries current away from the appliance. Resistance is a measure of how hard it is for the current to flow through the circuit. When live wire touches neutral wire due to defect, worn out, or damaged wiring, the resistance becomes zero, and a large current flows through it, there will be a short circuit.
Get PriceThe reason you''re seeing such a large range is because a battery is better thought of as a fixed voltage source, not a current source. If you have a 12V battery and you''re asking how much amperage can it kick out, the answer is however much or little it has to to satisfy Ohm''s law, V = IR. The less resistance you have in a circuit, the more current will flow and …
Get Price$begingroup$ A current impulse (infinite di/dt) can only pass through a perfect inductor if the terminal voltage across the inductor is infinite. In a practical world, an inductor has self-capacitance and this means the impulse current bypasses the "magnetic" side of things and appears to pass through the inductor, but it doesn''t theoretically.
