The importance of correct terminal connection lies in the polarity of the battery. The positive terminal carries a positive charge, while the negative terminal carries a negative charge. If the positive terminal connects to the negative cable and vice versa, it can reverse the battery''s direction of current.

Direction of current and direction of flow of electrons

TL;DR: By convention, current is assumed to travel from positive to negative direction. The electrons travel from negative to positive. The direction of current is not the same as direction of flow of electrons; they are opposite.

Positive and Negative Current

Current flows from the positive to the negative end of a battery or power supply. This is how it is written, described and measured. So, for example, if you are calculating the magnetic field caused by a current - the direction of the

current

A negative charge flowing from negative to positive is also a positive current; the negative sign from going the opposite direction and the negative sign from opposite charge combine to give a positive current. "Positive" and "negative" are a bit misleading, as there''s no "absolute zero" of voltage.
