What is sensor, resistor, plc program

Question

Accepted Answer

A sensor is a device that detects and responds to a physical input, a resistor is an electrical component that limits the flow of electric current, and a PLC program is a set of instructions for a programmable logic controller.

A sensor is used to measure and detect changes in physical properties such as temperature, pressure, light, etc.
Resistors are used to control the flow of electric current in a circuit and are often used to limit current or divide voltage.
A PLC program is a sequence of instructions written in a programming language specifically designed for programmable logic controllers.
PLC programs are used to control and automate industrial processes, such as manufacturing assembly lines or power plants.
For example, a temperature sensor can be used to monitor and control the temperature in a room by sending signals to a PLC program, which then adjusts the heating or cooling system accordingly.
