### Network Theory Objectives PART 01

**01 . **A nonlinear network does not satisfy** both homogeneity and super position condition.**

**02 . ** An ideal current source has **zero internal conductance.**

**03 . ** A terminal where three or more branches meet is known **as node.**

**04 . ** A closed path made up by several branches of the network is known as **loop.**

**05 .** Vacuum tube, transistor and filament bulb shows **nonlinear V-I characteristics.**

**06 . ** Kirchhoff law can be applied to both **AC and Dc circuits.**

**07 . **Generally, **abscissa refer to the horizontal axis and ordinate refers to vertical axis.**

**08 . ** If abscissa refer to current and ordinate refers to voltage,** characteristic of ideal current is vertical line**

**09 . **An ideal voltage source has **zero internal resistance.**

**10 . ** Capacitor is **passive and bilateral.**

**11 .** Constant voltage source **is active and unilateral.**

**12 . ** A network which contain one or more than one source of emf is known as **active network.**

**13 . ** Inductance of the coil can be increase by using** core material of high relative permeability , or b**y **increasing no of turns or by decreasing length of the coil **.

**14 . ** Air gap provided in the iron core of an inductor

**prevents core saturation.**

**15 .** Inductor stores energy in **magnetic field. **

**16 .** Current through the inductance follows **exponential growth.**

**17 . ** Reciprocal network is one in which transmission of signal between any two ports **does not depend on the direction of propagation. Input and output can be interchangeable.**

**18 . ** The condition** AD-BC=0** for two port network applies that network is** reciprocal.**

**19 . ** At t=0+** inductor act as open circuit and capacitor act as short circuit (** with no initial conditions)

**20 . ** At t=infinity** inductor act as short circuit and capacitor act as open circuit.**
