Easy V = IR problem, just help understand it.
When a battery is short-circuited, it means that the positive and negative terminals of the battery are connected directly, without any external resistance in the circuit. This allows for a large amount of current to flow through the battery, as there is no resistance to limit it.
Assertion (A) Reason (R) when a battery is short circuited, terminal voltage is zero. In short circuit, the current …
Potential difference accross the terminals of a non ideal battery is :-(A) zero when it is short circuited (B) less than its emf when current flows from negative to positive terminal inside the battery (C) zero when no current is drawn from the battery (D) greater than its ...

Short Circuiting a Battery: What Happens Next
A short circuit fault inside a battery can release a current thousands of times larger in milliseconds. This can irreparably damage all devices in the external …
Short circuit
OverviewDefinitionExamplesDamageRelated conceptsSee alsoExternal links
A short circuit is an abnormal connection between two nodes of an electric circuit intended to be at different voltages. This results in an electric current limited only by the Thévenin equivalent resistance of the rest of the network which can cause circuit damage, overheating, fire or explosion. Although usually the result of a fault, there are cases where short circuits are caused intentionally, for example, for the purpose of voltage-sensing crowbar circuit protectors.
What is the voltage and current of a shorted secondary of a …
In circuit theory, the definition of a short circuit is 0 V across its two terminals. In your example, this would mean you are forcing an infinite current through the transformer''s output (and, as a consequence, through the input, too), because the short is reflected to the ...

The basics of short circuits in power electronics systems
(Bild: GKV- stock.adobe ) In general, the term short circuit is commonly used to refer to a situation whereby a live or ''hot'' wire carrying a current comes into contact with a neutral wire. This article explains the several types, causes, and consequences of short circuits in power electronics.
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. …
