L L o o oo L L L L o L. A diode is a semiconductor device, usually constructed of silicon, that functions as a one-way switch for current. It lets current to flow smoothly in one direction while significantly restricting current from flowing in the opposing direction. Diodes are also known as rectifiers because they change alternating current (AC) into pulsating direct current (DC)..

A diode is a semiconductor device, usually constructed of silicon, that functions as a one-way switch for current. It lets current to flow smoothly in one direction while significantly restricting current from flowing in the opposing direction. Diodes are also known as rectifiers because they change alternating current (AC) into pulsating direct current (DC).

FUNCTION. Diodes have polarity, which is defined by the anode (positive lead) and the cathode (negative lead). Most diodes only allow current to flow when a positive voltage is applied to the anode. When a diode enables current to flow, it is forward biassed. When a diode is reverse-biased, it functions as an insulator, not allowing current to flow.. 

Scene 3

Diodes have polarity, which is defined by the anode (positive lead) and the cathode (negative lead). Most diodes only allow current to flow when a positive voltage is applied to the anode. When a diode enables current to flow, it is forward biassed. When a diode is reverse-biased, it functions as an insulator, not allowing current to flow.

Strange but true: the diode symbol's arrow points in the opposite direction of electron flow. Current flows from the positive (+) to the negative (-) side of the voltage source, as shown in the schematic. The same convention applies to semiconductor symbols with arrows: the arrow points in the permissible direction of "conventional" flow and against the permitted direction of electron flow.

OR GATES. Defination: A logic gate is a component that serves as a foundation for digital circuits. They perform basic logical processes that are essential in digital circuitry. Most of the technological devices we use today use logic gates. In a circuit, logic gates operate by combining digital signals from their inputs. Most logic gates have two inputs and one output, and they use Boolean algebra. At any one time, each terminal is one of two binary states: true or false. False represents 0; true represents 1. Function: The OR gate is named by its behavior, which resembles the logical inclusive "or." If either of the inputs is true, the result will be true. If both inputs are false, the result is false. In other words, if the output is 1, at least one of the inputs must be 1. according the diagram below can figure out if any respond from input either input 1 nor input 2 will reflect on output. Opposite if doesn’t any input it would not reflexes in output..

PRO AND CON. OR gates are essential components in electronic circuits due to their versatility, flexibility, and cost-effectiveness. They can be used in a variety of applications like data processing, control systems, and logic circuits. Their ability to handle multiple inputs allows for adaptable system design. OR gates are inexpensive, simple to implement, and fast, making them ideal for highspeed applications. Additionally, they are reliable when used within specified voltage and current limits. These qualities make OR gates a valuable asset in electronic circuit design. OR gates, while offering benefits like versatility, cost-effectiveness, simplicity, and reliability, also have several disadvantages. Their limited functionality restricts them to only performing the logical OR operation. The output voltage may be constrained by input levels, causing compatibility issues. Additionally, OR gates can produce signal noise or glitches, especially in high-speed applications. They also have notable power consumption and heat dissipation issues, particularly in large or high-speed circuits, which can impact efficiency and performance. These factors should be carefully considered when using OR gates in electronic systems..
