Measuring a floating dc voltage using a microcontroller’s analog-to-digital converter (ADC), with the dc+ to dc– ranging from 2.5 to 30 V and the low side able to float as high as 120 V above logic ...

Voltage is a measure of the difference in energy between one part of a circuit and another. It tells you how much electrical energy has been converted into other forms of energy. Voltage is measured ...
