The Potential Difference or Voltage Drop can be considered the voltage difference between any two points in a circuit. It is also the difference in electric potential between the final and the initial ...

When measuring current with a shunt resistor, what side of the load do you put it on? If you're amplfying the voltage drop across the sense resistor and digitizing that voltage, it makes a difference.

Telcom, LDMOS, automotive and many other applications require the measurement of current flow at high voltages (high-side current). Often, a circuit operating at 5 V must monitor currents at 48 V.

I once read this very strongly-written essay about the difference between electromotive force (EMF) and voltage. The author seemed like he was on some kind of holy crusade and was intensely determined ...
