Definition: "Anodal" refers to a single point where two or more points come into contact in an electric circuit, forming a current. "Anode" is a part that has a positive charge, while "donal", "neutral", "bivalent" are terms referring to those parts with no significant electrical charge. The term "anodal" describes the physical phenomenon where one point in a conductor or circuit causes another point to be negatively charged as an electric current flows through it.
