What is the difference in meaning of a voltage signal and current
A common example is the industrial 4-20 mA sensor standard. The data is encoded by allowing from 4 to 20 mA to flow, but the voltage can vary over a range. No signal is truly a voltage or current signal entirely. We simply name them that way because certain signals are closer to an ideal current or ideal voltage source.

Current Sensing Circuit Concepts and Fundamentals
A current sensor is a device that detects and converts current to an easily measured output voltage, which is ground. Normally, the sensed voltage signal (VSEN =ISEN × RSEN) is so small that it needs to be amplified by subsequent op amp circuits (e.g., non- and battery current monitoring. This section discusses three typical high-side

Difference between analog signal and battery voltage
Because I don`t have the sensor yet, I need to simulate its output. This can be assumed to be a constant DC voltage, since it will change very slowly. A reasonable value for this voltage is 2.25VDC. My approach to model my sensor is to take a 9V battery and load it with four 220K ohm resistors in series.
