The Main Difference between Active and Passive Components (Very Easy Explanation with Examples)

The Main Difference between Active and Passive Components

Active and Passive Commonest (Very Easy Explanation with Examples)
Active Components:
Those devices or components which required external source to their operation is called Active Components.
For Example: Diode, Transistors, SCR etc…
Explanation and Example: As we know that Diode is an Active Components. So it is required an External Source to its operation.
Because,  If we connect a Diode in a Circuit and then connect this circuit to the Supply voltage., then Diode will not conduct the current Until the supply voltage reach to 0.3(In case of Germanium) or 0.7V(In case of Silicon). I think you got it :)
Passive Components:
Those devices or components which do not required external source to their operation is called Passive Components. 
For Example: Resistor, Capacitor, Inductor etc…
Explanation and Example: Passive Components do not require external source to their operation.
Like a Diode, Resistor does not require 0.3 0r 0.7 V. I.e., when we connect a resistor to the supply voltage, it starts work automatically without using a specific voltage. If you understood the above statement about active Components, then you will easily get this example. :)The Main Difference between Active and Passive Components (Very Easy Explanation with Examples)In other words:
Active Components:
Those devices or components which produce energy in the form of Voltage or Current are called as Active Components
For Example: Diodes Transistors SCR etc…
Passive Components:
Those devices or components which store or maintain Energy in the form of Voltage or Current are known as Passive Components
For Example:  Resistor, Capacitor, Inductor etc…
In very Simple words;
Active Components: Energy Donor
Passive Components: Energy Acceptor
Also Passive Components are in linear and Active Components are in non linear category.

  1. Hi Admin,<br />Thanx for great efforts on this.<br /><br />I am confused with Diode.I&#39;ve seen many sites as it is passive component.Whether the diode is active component or passive component.

    1. Electrical Technology says:

      Diode is an Active component

    2. Passive devices don’t deliver power they on accept power. Active devices deliver power. Batteries deliver power. Diodes are passive devices.

    3. Actually semi conductor diode , Zenar diode are all active components .So i think that diode is an active component

  2. what do u mean by diode producing energy?? <br />the explanation is vague above…plz eloborate<br />

    1. Anonymous says:

      isnt it? diode can be L.E.D. and L.E.D emit light

    2. Anonymous says:

      so how do u xplain with diode alone, leaving apart L.E.D? also doesnt LED require a source for its operation?<br /> even a bulb gives out light energy when applied to a source, does that make bulb an active component?<br />can u make it clear to me?

    3. Anonymous says:

      bulb z a type of resister,so it z a passive component.i think u got me…

      1. saravanababu s says:

        what is the difference between dependent and independent semiconductors?

  3. Yeah! These explanations are very vague! Active components don&#39;t HAVE to produce power, and Passive components don&#39;t HAVE to store charge. A resistor does NOT store charge, it merely lessens the current flow.

    1. Anonymous says:

      thats why he said OR maintain energy. resistor like u said, lessens the current flow. isnt it part of maintaining the energy?

  4. Tariq Rajha says:

    how resistor is energy donar??? can u explain it a bit

    1. Electrical Technology says:

      Read it carefully.<br />&quot;Energy Donner or Maintainer&quot;

  5. You said devices which produce energy are called active components, on the other hand, you said active components are energy aceptors?<br />sorry I really can&#39;t get it!

    1. Electrical Technology says:

      Dear Learner@<br />Plz read it carefully

  6. Anonymous says:

    what is the difference between linear and non linear category?<br />

    1. Electrical Technology says:

      Nice Question….Wait for the upcoming Posts… Stay tune. Thanks

  7. Vinod Chemmangattu says:

    Very good explanation. thank you for sharing it… you are a good teacher…

  8. hello! Wanna ask to please broaden the explanation. Im still confused

  9. Anonymous says:

    Please read the explanation carefully before u comment….dumbheads

  10. chaudhary atiq says:

    The capacitor stores charge initially and then it starts conducting, why is it not an active component then, like the diode which does not start conducting till it gets 0.7 volt for itself.

    1. Electrical Technology says:

      it is not about conducting…but working &amp; Operation!<br />except ideal case, in 1st, 2nd &amp; 3rd approximation, we assume that diode will never conduct until it gets 0.7V.. I.e we assume that it is not in working mode… whereas, in case of capacitor… it direct operates when we give supply to the capacitor terminals… no matter what is its working,,,, Storing charge or conduction of

      1. Almaflor Brigildo says:

        oh your answer is very correct thank you because you helping people who did what is the answer

  11. Actually, the direction of Voltage & Current defines component type.
    If current flows from +ve to -ve potential => Passive
    If current flows from -ve to +ve potential => Active
    R=> Always Passive
    L , C => Sometimes Active & sometimes Passive


  13. Awesome yaar… i was little confused b/w active and passive components. but it is no longer. You have specified it in very easy way. Thanks!

  14. I really like your style keep it up

  15. Chethan S says:

    Good clarity on explanation provided :)

    It’s my future

  17. Aritonang says:

    No you are going to have to rerun all new service. Its not hard. first go and buy the breekar and wire you need. you can get that at your local hardware store. take the face of your service pannel off ( be carefull people die from this stuff.) you should have room to expand add the 230 breekar in it justs pops in run your wires red and black go to the breekar and are hot and the bare one will go to the neutral ground bar. and just wire it up from there. if this seems to dificult hire a professional to do it.

  18. electrons flows.phase to nutral or nutral to phase.plz explain.
