Self-contained breathing apparatus, used in open-circuit SCUBA
An electrical circuit is an "open circuit" if it lacks a complete path between the positive and negative terminals of its power source. Open circuits have infinite electrical resistance.

Open-circuit voltage or OCV is the difference of electrical potential between two terminals of a device when there is no external load connected, i. ... SCUBA is an acronym for Self-Contained Underwater Breathing Apparatus. ... // SCBA redirects here. ... Electrical resistance is a measure of the degree to which an electrical component opposes the passage of current. ...

TRANSFORMER EQUIVALENT CIRCUIT (797 words)
	In electrical engineering, it is often useful to use an equivalent circuit model to describe the non-ideal operation of a device such as a transformer.
	As an example of the usefulness of the non-ideal equivalent circuit, the parameters found in the lab are used to calculate one important transformer characteristic, maximum efficiency.
	With the secondary open, the primary voltage was increased from zero to rated voltage, where the rated voltage is the name plate stamp.
