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 by 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.
