What is a linear element?
An electrical network, a linear element shows
the linear characteristics in between voltage & current. That is the
current passing through a linear element is changed according to the change in
the voltage across its terminals.
An important phenomenon of any linear element is the properties
of the linear element do not change with the change of applied voltage or the
circuit current. Resistors, inductors, capacitors are linear elements as their
resistances, inductances, capacitance do not change with a change in applied
voltage or the circuit current.
A circuit which is made with only linear elements, is called
linear network. Sometime this type of circuit is very useful where voltage
versus current relationship should remain linear & any signal distortion is
not required.
