Electricity finds the lazy shortcut home, and your device pays the toll.
means An unintended low-resistance path in an electrical circuit that lets current skip the intended load and surge where it shouldn't, often damaging the circuit or causing it to fail.
from Straightforward engineering language: 'circuit' from Latin circuitus, 'a going around,' describing the closed loop a current travels. 'Short' here means abbreviated — the current finds a shorter, easier route than the one designed for it. The phrase dates to 19th-century electrical engineering, and by the mid-1900s had jumped into everyday speech for any process that skips its proper steps — 'his thinking short-circuited' — borrowing the literal image of power taking a shortcut and blowing something out along the way.

- low-resistance path skips the intended circuit load
- the danger
- current spikes fast, heat follows faster
- fuse purpose
- sacrifices itself before wires do
- brain slang
- borrowed to mean sudden mental overload too
