Short circuit

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 …

thermodynamics

I would like to point out that, except in the movies, it isn''t the case that "When a short circuit occurs it''s obvious that there is fire".. Now it is true that, for most, "short circuit" evokes a picture of sparks and fire but, in fact, most short circuits simply result in a malfunctioning device, not sparks and fire. A practical notion of "short circuit", in this context, is an …

Short Circuit: Physics & Electricity Science Activity

Thus most of the resistance of the circuit is in the steel wire. When you connect the clip to the steel wire, the voltage of the battery pushes electrons through the circuit against the resistance of the steel wire, causing the steel wire to heat up. As you move the clip closer to the battery, the resistance of the steel wire decreases.
