What is an OR Gate?


OR Gate Definition


An OR gate is defined as a logic gate that outputs high (1) if one or both inputs are high (1).

Working Principle


The working principle of an OR gate is to find the maximum between binary digits, resulting in a high output if any input is high.


 

Truth Table


The truth table of an OR gate lists the output for all possible input combinations, showing how the gate responds.

Diode Circuit


A diode can be used to create an OR gate, where any high input makes the output high.

Transistor Circuit


Transistors can also form an OR gate, providing a high output if any transistor is switched on.

Battery charging process using AC adapter
Battery charging process using AC adapter
The process of charging the battery using the AC adapter is as followsConnecting devicePlug the AC adapter into the power outlet, making sure the connection is secure and stable. At this point, the AC adapter starts to obtain AC power from the grid.Connect the output of the AC adapter to the device that needs to be charged, usually through a specific charging interface or data cable.Ac adapter operationInput AC conversionThe circuit inside the AC adapter first rectifies the input AC power, conve

The circuit working principle of one-way switch
The circuit working principle of one-way switch
A one-way switch is the most basic type of switch that has only one input (often called the "normally on" or "normally closed" state) and one output. The working principle of the one-way switch is relatively simple, but it has a wide range of applications in various electrical and electronic devices. The following details the circuit working principle of the one-way switch:The basic structure of a one-way switchA one-way switch usually consists of the following parts: Contact: A metal part used

What is the effect of applying alternating current to a DC machine?
What is the effect of applying alternating current to a DC machine?
Applying alternating current to a DC motor can have a variety of adverse effects because DC motors are designed and operate to handle direct current. The following are the possible effects of applying AC to a DC motor:Cannot start and run properly No natural zero crossing: AC has no natural zero crossing to help the motor start, while DC motors rely on constant direct current to establish a magnetic field and start. Inversion phenomenon: The sinusoidal waveform of alternating current changes dir
