Voltage and Current Divider Rule

Voltage and Current Divider Rule: Voltage and Current Divider Rule is explained by two conditions, namely Voltage Division in Series Circuit of Resistors Current Division in Parallel Circuit of Resistors Voltage Division in Series Circuit of Resistors: Consider a series circuit of two resistors R1 and R2 connected to source of V volts is shown […]

Ladder Network Circuit Analysis

Ladder Network Circuit Analysis: By using this Ladder Network Circuit Analysis, we can find the equivalent resistance by Continued Fractions Method. Consider a Ladder Network Circuit as shown in the Fig. 1.40. Let us calculate equivalent resistance by series parallel method first. So (t + u) is in parallel with s. The combination is in

Nodal analysis

Nodal analysis: This Nodal analysis method is mainly based on Kirchhoff’s Current Law (KCL). This method uses the analysis of the different nodes of the network. We have already defined a node. Every junction point in a network, where two or more branches meet is called a node. One of the nodes is assumed as

Loop Analysis with Current Source

Loop Analysis with Current Source or Mesh Analysis: This method of Loop Analysis is specially useful for the circuits that have many nodes and loops. The difference between application of Kirchhoff’s laws and loop analysis is, in loop analysis instead of branch currents, the loop currents are considered for writing the equations. The another difference

Source Transformation Technique

Source Transformation Technique: Sometimes in the complex network, both the energy sources may be present. But in loop analysis, all the energy sources should be preferably voltage sources and in node analysis, all the energy sources should be preferably current sources. The source transformation technique is useful in converting voltage to current source transformation and current

Cramer Rule

Cramer Rule: If the network is complex, the number of equations i.e. unknowns increases. In such case, the solution of simultaneous equations can be obtained by Cramer Rule for determinants. Let us say that set of simultaneous equations obtained is, as follows :   Then Cramer’s Rule says that form a system determinant Δ or

AC Fundamentals

AC Fundamentals: Let us discuss in brief, the AC Fundamentals necessary to analyse the networks consisting of various alternating current and voltage sources, resistances and inductive, capacitive reactances. An alternating current or voltage is the one which changes periodically both in Cycle magnitude and direction. Such Change in magnitude and direction is measured in terms

Types of Energy Sources

Types of Energy Sources: There are basically two Types of Energy Sources ; voltage source and current source. These are classified as i) Ideal source and ii) Practical source. Let us see the difference between ideal and practical sources. Voltage Source Ideal voltage source is defined as the energy source which gives constant voltage across

Circuit Elements

Circuit Elements: Let us take a brief review of three basic Circuit Elements namely resistance, capacitance and inductance. Resistance It is the property of the material by which it opposes the flow of current through it. The resistance of element is denoted by the symbol ‘R’. Resistance is measured in ohms (Ω). The relation between
