            TEXT B. ACTIVE AND PASSIVE COMPONENTS
          
        
        
          
            Brainstorm:
          
        
        
          What do we understand by active and passive components?

          Electronic components are the elements of circuit which helps in its
        
        
          functioning. Active and passive components form the two main types of
        
        
          electronic circuit elements.
        
        
          An active component is an electronic component which supplies energy
        
        
          to a circuit. Active elements have the ability to electrically control electron flow
        
        
          (i.e. the flow of charge). All electronic circuits must contain at least one active
        
        
          component. Common examples of active components include:
        
        
          Voltage sources
        
        
          Current sources (e.g. DC current source)
        
        
          Generators (such as alternators and DC generators)
        
        
          All different types of transistors (such as bipolar junction transistors,
        
        
          MOSFETS, FETs, and JFET)
        
        
          Diodes (such as Zener diodes, photodiodes, Schottky diodes, and LEDs)
        
        
          A passive component is an electronic component which can only receive
        
        
          energy, which it can either dissipate, absorb or store it in an electric field or a
        
        
          magnetic field. Passive elements do not need any form of electrical power to
        
        
          operate. As the name ‘passive’ suggests – passive devices do not provide gain
        
        
          or amplification. Passive components cannot amplify, oscillate, or generate an
        
        
          electrical signal. Common examples of passive components include:
        
        
          Resistors
        
        
          Inductors
        
        
          Capacitors
        
        
          Transformers
        
        
          Transducers, sensors, detectors
        
        
          Antennas
        
        
          Assemblies, modules
