elements which satisfy superposition principle are said to
be linear elements.otherwise they are nonlinear elements.
in a simplest way, for linear elements the V and I
relationship should be linear i.e the releation should be
straight line which is passed through the origin. examples
for linear elements are R, L, C etc. but where as Diode is
a nonlinear element. it follows square law.transistor also
comes under nonlinear element category.
linear elements are those which obey Ohms law.for example
resistor,capacitor,inductor etc.it hav a characterics
containing a straight line passing through the origin with
a definite slope.
nonlinear elements are those which doesnt obey Ohms law.for
example diode ,transistor etc
the examples of linear elements are Resistor,capacitor and
inductor....and the examples for non-linear elements are
diodes and transistors....and the graph for the linear
elements passes through the origin....
Linear elements are resistor,capacitor,inductor,transformer.for linear element there should exist linear relationship between voltage and current. i.e They change linearly with respect to each other.The graph is a straight line.
Non linear elements are diode,transistor. i.e semiconductor devices.The relationship between voltage and current is non linear (i.e not straghtline).
. A superconductor is a
a.) A material showing perfect conductivity and Meissner
effect below a critical temperature
b.) A conductor having zero resistance
c.) A perfect conductor with highest di-magnetic susceptibility
d.) A perfect conductor which becomes resistance when the
current density through it exceeds a critical value
