Yep, open in electrical terms means open-circuit... essentially this means there is no electrical conductivity between point A and point B in a circuit indicating the circuit is broken due to a failed wire, trace, joint, or component, or in the case of a component such as a capacitor, the component no longer has electrical continuity (as it has failed) and may as well not exist.

I find these results unsurprising but nonetheless fascinating to see put to paper.
