Inductors

Inductors are another basic building block of electronic circuits. Like resistors, they tend to impeded current flow. Notice they tend to impeded current flow. However, the opposition offered by inductors is different for AC and DC circuits. What we will find is that they offer a great deal more impedance to AC than they do to DC. In fact, with DC we'll find that they offer almost no impedance and that the impedance they offer to AC has a lot to do with what is the frequency that we're sending through that inductor. Inductors may also be called chokes or coils. The term choke refers to how inductors can be used to suppress undesired frequencies. Electromagnetic induction is at the heart of inductor theory of operation.
