This has come to be known as conventional current flow. Then in 1897, British physicist Thompson, discovered that current flow was really electrons as he was doing some research on a crt.

Advanced Auto-Qualified Current-Shunt Monitors Addressing these needs, Diodes Inc. introduced the ZXCT18xQ series of automotive-compliant, high-precision current-shunt monitors (see figure).

Which way does electricity flow through a vehicle’s electrical system? From positive to negative, or from negative to positive? Depending on your viewpoint, it can flow either way.

For unidirectional current flow, the REF-pin of the ZXCT181Q is tied to GND. The ZXCT18xQ series has four fixed voltage gain options—20V/V, 50V/V, 100V/V, and 200V/V.
