Inductor and Transformer Symbols

2.5.2025
Reading Time: 14 mins read
A A

This article provides overview of common and less common inductor and transformer symbols.

The inductors, coils or chokes are electrical passive components that have a certain number of turns of wire that introduce magnetic inductance to an electrical circuit to produce a magnetic flux or to mechanically react to magnetic flux variations.
