What is importance of equivalent circuit?

An equivalent circuit is a very useful way of understanding or predicting the operation and behaviour of an electrical circuit or apparatus. It requires the deconstruction of the circuit into ideal simple circuit elements – e.g. resistors, inductor, capacitors, rectifiers, voltage and current sources.

What is equivalent circuit?

Definition of equivalent circuit : an electric circuit made up of the basic elements resistance, inductance, and capacitance in a simple arrangement such that its performance would duplicate that of a more complicated circuit or network.

What is the main advantage of Thevenin and Norton equivalent circuits?

Advantage Of Thevenin Theorem It reduces a complex circuit to a simple circuit viz a single source of e.m.f. Eth in series with a single resistance RTh. It greatly simplifies the part of the circuit of the lesser importance and enables us to view the action of the output part directly.

What are the parameters of the equivalent circuit?

In the case of a short-circuit test, the equivalent circuit consists of the sum of the transformer primary winding impedance, and the secondary winding impedance reflected to the primary side, RCU and XR.

What is equivalent circuit parameter transformer?

In the equivalent circuit of a transformer, the voltage drop due to the primary winding series impedance is the phasor difference of the input voltage and the induced e.m.f. in the primary winding.

What is the advantage of Norton equivalent circuit?

Norton’s Theorem states that it is possible to simplify any linear circuit, no matter how complex, to an equivalent circuit with just a single current source and parallel resistance connected to a load.

What are the advantages and disadvantages of series combination?

What are the advantages and disadvantages of a series combination?

• Cells connected in series give a greater resultant voltage than individual cells.
• Voltage increases if the number of cells increases.
• Series circuits do not overheat easily.
