The Active and Passive components of electrical and electronics

 The Active and Passive component / element in Electrical & Electronics 

Here , if you see this word Active and Passive do you know that , what is the mean in electrical and electronics .

So let's first of all we learn to know that the , what is Active component / element in electrical and electronics ?

Active component / element : so , the active component or we can say that active element is capable of providing the energy independently for an infinite period of time , is called as or known as Active component / element .

                                             

Or 

we can defined Active component / element in other words that : the Active component or Active element is capable to provide an average power to some external device or we can say they electronic circuit , over an infinite period of time .

So take an example of this Active component / element : Battery , vacuum tube , voltage Source , Current Source , Transistor , Op-amp etc.

Passive component / element : so here , the passive component or we can say that in other words that , the passive element is not capable to providing the energy independently for an infinite period of time , is called as or known as passive component / element .

                                                    

Or

 we can define this Passive component / element : so in other words the passive component / element is define as , it is not capable to providing the energy independently for an infinite period of time , is called as or known as Active component / element .

So here in this Passive component / element we see the  examples of this is , Resistor , Capacitor , Inductor , Transformer , Diode , etc .

Let's see one by one concept of this passive component / element .

1) Resistor : As we know that , the Resistor is used to limiting the flow of electric current in the conductor , so as you know that it is only purpose of controlling the electric current only and it is not come in use to delivering energy independently for an infinite period of time .

                                                    

So the Resistor is energy dependent component or we can say that in other words that , it is energy dependent element .

2) Capacitor : so here as you know that , capacitor only store energy and releases energy when come in use . 

So here in this capacitor also you see that it is a energy dependent component or we can say that , energy dependent element .

                                                      

                                                           

3) Inductor : We know that about inductor , which it is a passive component / element which is very capable to storing the electrical energy in the form of magnetic energy .

So here we see in this inductor also , if we cut supply of electrical energy it stop storing energy in the form of magnetic energy . So it is also a energy dependent component or we can say they , energy dependent element .

                                                     

4) Transformer : The transformer work to " step-up " or " step-down " voltages and current . But frequency remain as it is or we can say that frequency remains constant .

But transformer also fail , if we cut off the supply source of voltage and current . Than it means that , these also is energy dependent component or we can say that energy dependent element .

                                          

5) Diode : So as above given those component or element , this diode also work when supply sources of voltage and current is connected . So here , this diode is make flow of current in unidirectional of alternate current ( A.C ) .

So simply it's mean that , these diode is also energy dependent component or we can say that in other words that , energy dependent element .
