The short circuit case is easy to detect with an electromagnet that will have a strong magnetic field when so much current flows. However, the overload case isn’t that abrupt.

Short circuits are relatively common, but they can be dangerous and a warning sign of a possible electrical hazard, so it's important to know what short circuits are and how to prevent them in ...

An old video card with an introduced capacitor short makes a good demo. The meter is able to tell where the short circuit is. The probes won’t win a beauty contest, but it looks workable.
