Substitution Theorem

Substitution theorem states that; If the value of current passes through the branch and the value of voltage across the branch is known, we can replace this branch with other elements like a voltage source, current source, different values of resisters, etc. by doing this, the initial condition remains unaltered.

What is compensation theorem?

The Compensation Theorem may be stated as follows: When the impedance of a branch of a linear network which carries a current I is modified by an amount oZ then all the currents in the network are altered by amounts equal to the currents which would arise if an e.m.f. -IoZ was acting independently in the modified

What is meant by reciprocity theorem?

Reciprocity in electrical networks is a property of a circuit that relates voltages and currents at two points. The reciprocity theorem states that the current at one point in a circuit due to a voltage at a second point is the same as the current at the second point due to the same voltage at the first.

What is superposition theorem?

The superposition theorem states that a circuit with multiple voltage and current sources is equal to the sum of simplified circuits using just one of the sources.

What are the advantages of substitution theorem?

The concept of the theorem is based on the substitution of one element from another element. This theorem gives intuition on the behaviour of the circuit. It also helps in proving several other theorems.

What is substituting method?

The substitution method is the algebraic method to solve simultaneous linear equations. As the word says, in this method, the value of one variable from one equation is substituted in the other equation.

What do you mean by Thevenin's theorem?

Thevenin's theorem states that it is possible to simplify any linear circuit, irrespective of how complex it is, to an equivalent circuit with a single voltage source and a series resistance.

What is the application of reciprocity theorem?

The reciprocity theorem is used to analyze the dynamic response to high-intensity heating of a small surface region. The particular example of line-focused laser-beam irradiation of one side of a homogeneous elastic plate is worked out in some detail.

How do you use Millman's theorem?

Using Millman's theorem, find the current through and the voltage across the load resistor; RL is shown in the figure.

1. Solution:
2. Step 1: Converting voltage source to current source by dividing with their respective resistance.
3. Step 2: Calculating the equivalent current.
4. Step 3: Calculating the equivalent resistance.

What is meant by Norton's theorem?

What is Norton's Theorem? 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 applications of superposition theorem?

It is used in converting any circuit into its Norton equivalent or Thevenin equivalent. The theorem is applicable to linear networks (time varying or time invariant) consisting of independent sources, linear dependent sources, linear passive elements (resistors, inductors, capacitors) and linear transformers.

What is reciprocity and symmetry?

A network is said to be reciprocal if the ratio of the response to the excitation is invariant to an interchange of the positions of the excitation and response of the network. A two-port network is said to be symmetrical if the input and output ports can be interchanged without altering the port voltages and currents.

Why do we use superposition?

If a circuit is made of linear elements, we can use superposition to simplify the analysis. This is especially useful for circuits with multiple input sources. To analyze a linear circuit with multiple inputs, you suppress all but one input or source and analyze the resulting simpler circuit.

What is Max power transfer formula?

Maximum Power Transfer Formula As shown in the figure, a dc source network is connected with variable resistance RL. The fundamental Maximum Power Transfer Formula is. P m a x = V T h 2 4 R T h.

Who invented superposition theorem?

According to Léon Brillouin, the principle of superposition was first stated by Daniel Bernoulli in 1753: "The general motion of a vibrating system is given by a superposition of its proper vibrations." The principle was rejected by Leonhard Euler and then by Joseph Lagrange.

What is the advantage of Thevenin's theorem?

Advantages of Thevenin's Theorem It simplifies the portion of the circuit of lesser importance and enables us to directly view the action of the output part. It reduces a complex circuit to a simple circuit that isa single source of emf in series with a single resistance.

What are the application of Norton's theorem?

The Norton equivalent circuit is used to represent any network of linear sources and impedances at a given frequency. Norton's theorem and its dual, Thévenin's theorem, are widely used for circuit analysis simplification and to study circuit's initial-condition and steady-state response.

What are the limitations of Tellegen's theorem?

The circuit having time varying element then the reciprocating theorem is not applicable. The circuits having dependent source even it is linear then the reciprocating theorem is not applicable. The circuit having non linear element like diode transistor then reciprocating theorem is not applicable.

What is substitution method with example?

The first step in the substitution method is to find the value of any one of the variables from one equation in terms of the other variable. For example, if there are two equations x+y=7 and x-y=8, then from the first equation we can find that x=7-y. This is the first step of applying the substitution method.

How do you use substitution?

The method of solving "by substitution" works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other. Then you back-solve for the first variable.
