Introduction to Diodes And Rectifiers

A diode is an electrical device allowing current to move through it in one direction with far greater ease than in the other. The most common kind of diode in modern circuit design is the semiconductor diode, although other diode technologies exist. Semiconductor diodes are symbolized in schematic diagrams such as Figure below. The term “diode” is customarily reserved for small signal devices, I ≤ 1 A. The term rectifier is used for power devices, I > 1 A. Semiconductor

Uses of a Diode

Uses of a Diode Diodes are semiconductor devices that effectively block current in one direction while allowing current flow in the other. An ideal diode, therefore, acts like a switch that is open in one direction and closed in the other. Diodes are enclosed in cases such as glass or plastic that are marked with a band to indicate the cathode side. Current flow from the anode to cathode means the diode is forward-biased, while current flow from the cathode

Capacitors

What Are Capacitors Used for? Electronic circuits use capacitors to store and release electricity in controlled amounts. These components consist of a pair of metal foils separated by a thin insulator. A voltage on the foils creates an electric field in the insulator, storing electrical energy. It takes time to charge a capacitor, so they serve as parts of timing circuits. Their energy-absorbing ability helps to smooth out noisy electrical signals. Power Supplies Almost all electronic devices have a power
