Web4 Answers Sorted by: 10 A short is never actually a true short. It's a very low resistance. So even if you made two "shorts" one could be 0.25 Ohms and the other could be 0.001 Ohms. Depending on the circuit, they're both shorts, but they could act very differently depending upon the amount of current coming from the circuit. WebShort circuit– A shorthappens when a path of low resistance is connected (usually by mistake) to a component. The resistor shown below is the intended path for current, and the curved wire going around it is the short. Current is diverted away from its intended path, sometimes with damaging results.
