How are inductors and transformers represented in circuit diagrams?
1 Answer
Inductors and transformers are represented in circuit diagrams using specific symbols to indicate their presence and functions. Here's how they are typically represented:
Inductors:
Inductors are passive components that store energy in the form of a magnetic field when current flows through them. In circuit diagrams, the symbol for an inductor looks like a coil or a series of loops. The symbol consists of two terminal leads, and the coil is usually curved to distinguish it from other components. The following is the standard symbol for an inductor in a circuit diagram:

Transformers:
Transformers are also passive components used to transfer electrical energy from one circuit to another through electromagnetic induction. They consist of two or more coils wound around a shared magnetic core. In circuit diagrams, transformers are represented using two inductor symbols, with a dotted line or solid line connecting their cores to indicate the magnetic coupling. The number of turns in each coil might also be indicated using subscripts.
Here's the basic representation of a transformer with two coils, primary and secondary:

/___\ /___\
P2 S2
In the symbol above, P1 and P2 represent the two terminals of the primary coil, while S1 and S2 represent the two terminals of the secondary coil.
The actual circuit diagram may include additional markings for the number of windings in each coil, the direction of the windings, and other specifications depending on the complexity of the transformer and the level of detail required in the diagram.
Always refer to the legend or accompanying information provided in the circuit diagram to understand specific symbols and their functions accurately.
