What is the interpretation of dot convention in inductors?
n circuit analysis, the dot convention is a convention used to denote the voltage polarity of the mutual inductance of two components. Two good ways to think about this convention:
1. The current going into one dot (either dot) “tries” to come out the other dot. “Into” meaning from the dot toward the inductor, and conversely “out” meaning from the inductor toward the dot.
2. Current going into a dotted terminal of the inductor induces a positive voltage at the other dot. Conversely, current leaving a dotted terminal inductes a negative voltage at the other dot.
