simulate this circuit – Schematic created using CircuitLab. The voltage across R ohm should be always V volts for every single value of R except R=0 and at that resistance the current through R needs to be infinite to get rid of all energy and reduce the potential energy to become same with the negative terminal (or 0 joule).
Learn More''short-circuits'' and ''battery damage'' are a concern of drawing too much current from a power source like a battery. So first question: how much current can you safely draw from the battery? Also a design decision here is making sure the wiring between the battery and the nichrome, and the connections, are sufficient to handle high currents ...
Learn MoreBear in mind that infinite resistance is equal to an open circuit. In real life if you have a battery not connected to anything, there will always be a voltage across the terminals. Even a lead-acid car battery will produce sparks if you short the terminals!

Learn MoreSafety has become an increasingly pressing issue in large-format, energy-dense Li-ion batteries for automotive applications. Among various abusive scenarios for Li-ion batteries, internal short-circuit is most dangerous and has been the root cause for several highly publicized catastrophic accidents in recent years.
Learn MoreA battery short circuit occurs when a low-resistance path forms between the battery''s terminals, allowing excessive current flow. It can result from damaged wiring, corroded connections, or internal defects. Short circuits can lead to overheating, electrolyte leakage, and pose safety hazards. Identifying and addressing short circuits promptly is …

Learn MoreAccording to the magnitude of R sc, the short circuit can be roughly classified into two types: the major short circuit and the minor (micro-) short circuit. Note that the major short circuits, R sc is usually small (<10 1 Ω ).
Learn MoreA short-circuit means a circuit which is too short - usually unintentionally. Its resistance is so low that it takes too large a current, overloading the power source and/or overheating the wires. As cjl pointed out, the wire of the electromagnet is chosen to be long enough and thin enough for its resistance to be large enough for …

The zigzag symbol represents the single resistor and includes any resistance in the connections to the voltage source.
Learn MoreAll things have resistance. A short circuit is when there isn''t much resistance and as a result you end up with a ton of current. The size of a resistor that you use is dependent on the power supply you''re using. Many lab power supplies have a current limit that keeps them from putting out more than a certain amount of current.
