What is a reactor
2023-04-14
Reactors, also known as inductors, are widely used in circuits where there is a certain amount of inductance that can act to stop changes in current because of the effect of electromagnetic induction . When a conductor is energised it generates a magnetic field in a certain area of the space it occupies, so all electrical conductors capable of carrying current have inductance in the usual sense. However, the inductance of an energised long straight conductor is small and the magnetic field produced is not strong, so the actual reactor is a wire wound in the form of a solenoid, called a hollow reactor; sometimes, to give this solenoid a greater inductance, an iron core is inserted into the solenoid, called an iron core reactor. Reactors are classified as inductive and capacitive, and a more scientific classification is that inductors (inductors) and capacitors (capacitors) are collectively called reactors, however, as inductors existed first in the past and were called reactors, what people now call capacitors are capacitors, and reactors refer exclusively to inductors.
