What is the difference between passive and active components please?

Question

kenljw · Answer

A passive component have a definite reaction as resistance to voltage and current, or capacitors and inductor to voltage, current, and frequency.  Active components can be adjusted to have certain reactions as diodes, transistors, pentodes and the like.

Thank you!!

anonymous · Answer

passive components need power and active components give power

kenljw · Answer

Not true active components convert DC to signal power, if does not generate it.

ok my mistake, but thats what my teacher said. can you help me with my question

kenljw · Answer

Generally one misinterprets what others say because it was said to those learning considering them without a background to fully understand.  I sort of what Christ meant when he said "Let those with ears to hear let them hear".  This occurs in all subjects in which a background of knowledge is important for further understanding.

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)

active elements are sources........ passive elements consumes the power  which is delivered by sources
