What is the difference between active elements and passive elements

This artile explans the difference betwwen the active elements and passive elements with examples and relative pictures. "A network is an interconnection of two or more elements.If this interconnection involves at least one closed circuit,the network is also called as an electrical circuit".

The classification of network elements are 2 types

1.Active elements
2.Passive elements

    1.Active Elements : The elements which are capable of delivering energy to devices or networks connected across them are known as active elements .
Basically hee are two kinds of active elements as follows .
(i) Independent voltage source
(ii) Independent current source
(i)An independent vootage sourse is a sourse in which the voltage source us a source in which the voltage across the terminals is independent of current passing through it ,

The above figure shows the cicuit representation and V-I characteristics of an ideal sourse.The voltage source is termed as a D.C voltage sourse if it has a constant voltage and is represented as follows ,

The V-I characteristics of a practical voltage source is shown below .

(ii)An independent current sourse is asourse which can deliver a constant current independentof volatge across its terminals.The circuit representation and the V-I characteristics of an ideal current sourse are as shown below.

Practically,the current sourse doesnot posses an ideal behavior .The V-I characteristics of a practical current sourse is as shown below.

2.Passive Elements The elements which cannot deliver power and can only receive the power are known as passive elements.
Basically,there are three kinds of passive elements

(a) Resistor-which absorbs the energy

(b) Inductor-which stores the energy in magnetic field

(c) Capacitor-which stores the energy in an electric field
