The word “voltage” is so common now, in both technical and everyday contexts, that it’s a good idea to occasionally remind ourselves what voltage really is from a scientific perspective. Electric charge can do work in the world, and work is analyzed and quantified using the scientific. .
A negative voltage is not fundamentally different from a positive voltage; both represent potential energy relative to a reference potential. If a circuit node is at a positive voltage. .
Rudimentary circuits often begin with an unregulated power supply, for example, from a battery or wall transformer, that is reduced to 5 V or 3.3 V using a linear regulator. We cannot. .
Though many electronic devices accomplish their required functionality without a negative supply voltage, some applications. When power and current are 180° out of phase, the power reading is negative. Changes in phase relationship also have a bearing on the power factor reading. It is important to observe the markings on the CTs and the CT wire polarity. [pdf]
