Modeling of electric circuit Class presentation, You can also use it as a public or crowd. In this slide I'm explaining about Modeling of Electric Circuits. Actually I'm finding it on this platform but vain now I create my own self and decide to upload it for helping others. #modeling #Eclectric_Circuits #Conductor #Capacitor #inductor

3. ELECTRIC CIRCUITS:
An electronic circuit is composed of
individual electronic components,
such as resistors, transistors,
capacitors, inductors and diodes,
connected by conductive wires or
traces through which electric current

4. MODELING:
• A mathematical model is a description of
a system using mathematical concepts and language.
• The process of developing a mathematical model is
termed mathematical modeling. Mathematical models are used in
the natural sciences (such as physics, biology, earth
science, chemistry) and engineering disciplines (such as computer
science, electrical engineering), as well as in non-physical systems
such as the social sciences (such
as economics, psychology, sociology, political science).
• Mathematical models are also used in music, linguistics
and philosophy (for example, intensively in analytic philosophy).

5. MODELING:
•A model may help to explain a system and
to study the effects of different
components, and to make predictions
about behavior.

6. ELEMENTS IN AN RLC-CIRCUIT:

7. RESISTOR:
•In bellow the circuit model of resistor is shown
in Fig.
•The mathematical model is given by the
Ohm’s law relationship,

8. INDUCTOR:
•In bellow the the circuit representation is
shown in Fig.
•The input output relations are given by
Faraday’s law,

10. SELF-INDUCTANCE:
• If only a single coil is considered, the inductance is
known as self-inductance. If a voltage is induced in a
as second coil due to a current in the first coil, the
voltage is said to be due to mutual inductance, as
shown in Fig

11. CAPACITOR:
•In bellow the circuit symbol of a capacitor
is given in Fig.
•If we integration of v(t) is known as the
charge on the capacitor and is denoted
by ‘q’. Thus

13. FIGURE 1 EXPLANATION:
•Figure 1 shows an RLC-circuit, as it occurs
as a basic building block of large electric
networks in computers and elsewhere. An
RLC-circuit is obtained from an RL-circuit
by adding a capacitor.

14. ANALOGY OF ELECTRICAL AND
MECHANICAL QUANTITIES:
• Entirely different physical or other systems may have
the same mathematical model.
• This analogy is strictly quantitative in the sense that to
a given mechanical system.
• we can construct an electric circuit whose current will
give the exact values of the displacement in the
mechanical system when suitable scale factors are
introduced.

15. • The practical importance of this analogy is almost
obvious. The analogy may be used for constructing an
“electrical model” of a given mechanical model,

16. •In above discussion we can see the
Mathematical Modelling of Electrical Systems
which has come to act when we go for Laplace
transform. It will come to act when we will go
for calculate transient response of an electrical
systems in time domain.
•Hope this above discussion on Mathematical
Modelling of Electrical Systems will be
helpful to you.
