1.A representation of an actual electric circuit or
electronic device by a simple circuit whose behavior is very
near to that of the actual circuit over a specified range of
conditions is called as equivalent circuit.

2.The use of equivalent circuits is in analysis and design
operations associated with electronic circuits as it is
mainly composed of linear, passive elements.

3.Two of the best-known equivalent circuits are the Thévenin
equivalent circuit and the Norton equivalent circuit.

Answer / ishant

equivalent circuit actually used to represents large
electric circuits into simple circuits to study their behaviour

Answer / sacchidanand teke

Equivalent circuits can also be used to electrically
describe and model either
a) continuous materials or biological systems in which
current does not actually flow in defined circuits,
b) distributed reactances, such as found in electrical
lines or windings, that do not represent actual discrete
components.
For example, a cell membrane can be modelled as a
capacitance in parallel with resistance-DC voltage source
combinations

Answer / nishantmishra

we cant say that two best known circuits r norton and
thevenins test the abope is appropriate up to some extent.

Sir, I wish to appear for the written test in the year 2009. But i have no syllabus on the basis of that the exam was held. So if you kindly give me the syllabus,it's easy for me to be prepared. I have already registered through online,and that no is 10857
