Question

What is the importance of measuring current in the clockwise direction?

Answer 1

The convention of deciding the direction of current depends on the flow of elections(current flows opposite to the electron flow).

Current is the rate at which charge flows past a point on a circuit.
A current of 1 ampere means that there is 1 coulomb of charge passing through a cross section of a wire every 1 second.
Ben Franklin, who conducted extensive scientific studies in both static and current electricity, envisioned positive charges as the carriers of charge. As such, an early convention for the direction of an electric current was established to be in the direction that positive charges would move. The convention has stuck and is still used today. The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires in the opposite direction. Knowing that the actual charge carriers in wires are negatively charged electrons may make this convention seem a bit odd and outdated. Nonetheless, it is the convention that is used worldwide and one that a student of physics can easily become accustomed to.
Note that it's a convention that the direction of current will be in the direction of positive charge, but it's not that the direction of current is a clockwise or anti clockwise.It purely depends on the direction of flow of electrons.
