You would have infinite amperes if there was no resistance in the battery plates, the battery terminal posts and in the wires that are shorting the battery.
But there is always resistance in those things so - depending on the thickness and therefore the effective resistance of the wires that are shorting the battery - the short circuit current will be from a few amps to many hundreds of amps and, unless someone sees it and acts quickly to remove the cause of the short, that current will continue until the battery either explodes or just runs down very fast.
I've seen them go both ways, along with the shorting wires smoking and then glowing like an electric fire, and also I have seen molten globs of hot metal dripping off from carelessly misplaced tools such as heavy screwdrivers, particularly if made of aluminum, and such things as small wrenches.
What else can I help you with?
High current and low resistance are the conditions for a short is that true?
Yes, that's true. A short circuit occurs when there is a path of low resistance in an electrical circuit, allowing a high current to flow. This can happen when wires accidentally touch or when a component fails, causing excessive current that can lead to overheating and potential damage to the circuit or devices involved. Proper safety measures, such as fuses and circuit breakers, are essential to protect against short circuits.
Is short to voltage the same as short to ground?
No, short to voltage and short to ground are not the same. A short to voltage occurs when a component is connected directly to a voltage source, bypassing the normal circuit path, which can lead to excessive current flow and potential damage. In contrast, a short to ground happens when a circuit connects directly to the ground reference point, potentially causing a fault condition that can also lead to damage. Both scenarios can be hazardous, but they affect circuits differently.
What cause the voltage t lead current in an ac circuit?
Voltage leads current or, more specifically current lags voltage, in an inductive circuit. This is because an inductor resists a change in current.
What happens when you increase the size of the current?
When you increase the size of the current in an electrical circuit, the amount of charge flowing through the circuit per unit time increases, which can lead to a higher power output, as power is proportional to the product of current and voltage (P = IV). However, this can also result in increased heat generation due to higher resistance, potentially leading to overheating and damage to components. Additionally, if the circuit's components are not rated for the increased current, it may lead to failure or even short circuits.
When the secondary of a transformersudden short circuit the primary induction what?
When the secondary of a transformer experiences a sudden short circuit, it causes a drastic increase in current flow through the secondary winding. This results in a significant drop in secondary voltage due to the short circuit conditions. As a consequence, the primary winding will also experience a corresponding increase in current, which can lead to overheating and potential damage to the transformer if protective measures are not in place. The transformer's ability to handle this situation depends on its design and the effectiveness of protective devices such as fuses or circuit breakers.
Why a short circuit happen?
Presumably, the current follows a path (a circuit) to do whatever it was "made" to do. If water, for instance, enters the circuit, a shorter path may develop, and the current will (partially) take the short circuit. Or a wire could become lose and short circuit the intended path.
How does a short circuit work and what are its potential consequences?
A short circuit occurs when an electrical current takes an unintended path due to a direct connection between two points in a circuit with low resistance. This can lead to excessive current flow, overheating, and potentially cause fires or damage to electrical components.
Is a short circuit the easiest path for electricity to follow?
Yes, a short circuit provides the easiest path for electricity to flow because it bypasses the normal load and creates a low-resistance path between the two points. This can lead to high current flow and potential damage to the circuit or equipment.
High current and low resistance are the conditions for a short is that true?
Yes, that's true. A short circuit occurs when there is a path of low resistance in an electrical circuit, allowing a high current to flow. This can happen when wires accidentally touch or when a component fails, causing excessive current that can lead to overheating and potential damage to the circuit or devices involved. Proper safety measures, such as fuses and circuit breakers, are essential to protect against short circuits.
How can short circuit damage devices?
A short circuit can damage devices by allowing an excessive current to flow through the circuit, which can generate heat and potentially cause components to overheat or burn out. This can lead to damage to the device's components or even start a fire.
If your power supply has a current control how can it be used to minimize the possibility of a short circuit?
A power supply with current control can limit the maximum current output, reducing the risk of a short circuit by preventing excessive current flow that could lead to overheating or damage. By setting a predefined current limit, the power supply will automatically adjust its output to stay within safe levels, effectively protecting connected components. This feature helps ensure that in the event of a short circuit, the current remains manageable, minimizing potential hazards.
How does a resistor effect batteries in parallel and batteries in series?
In a series circuit, adding a resistor increases the total resistance, which can reduce the current flowing through the batteries, potentially extending their lifespan but also decreasing the overall voltage available to the load. In a parallel circuit, a resistor can limit the current through each branch, helping to balance the load across the batteries and preventing one battery from over-discharging. However, excessive resistance in a parallel setup can lead to insufficient current supply to the load. Overall, the resistor plays a critical role in managing current and protecting battery health in both configurations.
Do car batteries short out?
Yes, sometimes the lead plates will develop a short between themselves.
Why are batteries dangerous?
Not all types of batteries are dangerous. Alkaline batteries may explode if they have their poles inversely connected. Batteries used in vehicles contain lead and sulphuric acid that may be dangerous if inappropriately handled.
What does short to power mean?
"Short to power" is a term used in electronics to describe a circuit malfunction where an electrical short circuit causes excess current flow to the power supply, potentially damaging components. This can lead to overheating, fires, or other safety hazards. Proper circuit design and precautions such as using fuses can help prevent short to power situations.
Will the source voltage lead or lag the current in a circuit?
In an AC circuit, the source voltage can either lead or lag the current, depending on the type of load. Inductive loads cause the voltage to lag the current, while capacitive loads cause the voltage to lead the current.
What are the circuit effects due to a short circuit or open circuit?
It would depend on the circuit diagram. In some cases, the circuit would be incomplete (simplest case is a battery with a wire attached to just one terminal).Parallel branches that have a connection to the battery without going through other branches are independent of each other. Say you have two parallel branches and a battery. If you short circuit one of the branches, the other branch will not be affected but the battery will be (current through the battery would decrease because taking out a parallel branch increases resistance).In short, it would depend on the circuit diagram. Note that for a nanosecond, there would be current in an open circuit, but after this brief time there would be no current flow in the segment of the circuit that has been shorted.
