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

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. :)

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.

Thanx for great efforts on this.

I am confused with Diode.I've seen many sites as it is passive component.Whether the diode is active component or passive component.

1. Diode is an Active component

2. what do u mean by diode producing energy??
the explanation is vague above...plz eloborate

1. Anonymous07:40

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

2. Anonymous11:33

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

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

1. Anonymous07:41

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

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

"Energy Donner or Maintainer"

5. You said devices which produce energy are called active components, on the other hand, you said active components are energy aceptors?
sorry I really can't get it!

what is the difference between linear and non linear category?

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

2. Did you get it....
