Electrical Calibration for middle voltages

Electrical Calibration for middle voltages

Voltage Measurements. Voltage is the amount of electric potential, expressed in volts, between two points in a circuit. Usually one of these points is ground (zero volts), but not always. Voltages can also be measured from peak-to-peak. That is, from the maximum point of a signal to its minimum point.
