A relay is an electrically operated switch. It utilizes a coil of wire to activate a set of contacts, enabling the control of high-power circuits by means of a low-power signal. The construction of a relay typically involves a solenoid winding, a set of permanent contacts, and an armature which moves when energized. When current flows through the c

Capacitors are essential components in electronic circuits, and understanding their polarity is crucial for proper functioning. A capacitor consists of two check here conductive plates isolated by a non-conductive dielectric material. These plates have forward and bottom terminals, much like a battery. It's important to note that capacitors are de
