Learn more WhatsAppIf we classify these terms from a professional perspective, then the inductive reactor (inductor) and capacitive reactor (capacitor) are collectively referred to as reactors. The role of Reactors: Because so many different reactors do different things, they can be split into two groups based on how their circuits work: in series and in parallel.
Learn more WhatsAppA capacitor is an electrical component that stores energy in an electric field. It is a passive device that consists of two conductors separated by an insulating material known as a dielectric. When a voltage is applied across the conductors, an electric field develops across the dielectric, causing positive and negative charges to accumulate …
Learn more WhatsAppI wonder what the purpose of the coupling capacitors and the bypass capacitors are and the type of effect each capacitor has on the circuit. As I''ve understood it, you use coupling capacitors to block DC and avoid interference (what does that really mean?) and the bypass capacitor is to have a short-circuit in the emitter of the transistor …
