ELECTRONICS

Electronics involves the study of circuits and components that modify the intensity, direction or properties of electric currents.


ELECTRIC COMPONENTS


In this section, we will analyse the most common electronic components.


FIXED RESISTANCE OR RESISTOR


A fixed resistance or resistor opposes the flow of electric currents. Its value, which we measure in ohms, is indicated by a code of colours and numbers.





 


VARIABLE RESISTANCE OR POTENTIOMETER


The value of a variable resistance or potentiometercan be adjusted between zero and the máximum value specified by the manufacturer.
