In this section, we will briefly introduce some of the main topics covered in the book Network and Systems by D. Roy Choudhary.
Network Theorems
Network theorems are useful tools for analyzing and simplifying electric circuits. They are based on the principles of conservation of energy and charge. Some of the network theorems covered in the book are:
Superposition theorem: This theorem states that the response of a linear network to multiple sources is equal to the algebraic sum of the responses to each source acting alone.
Thevenin's theorem: This theorem states that any linear network with two terminals can be replaced by an equivalent circuit consisting of a voltage source in series with a resistor.
Norton's theorem: This theorem states that any linear network with two terminals can be replaced by an equivalent circuit consisting of a current source in parallel with a resistor.
Maximum power transfer theorem: This theorem states that the maximum power is transferred from a source to a load when the load resistance is equal to the source resistance.
Reciprocity theorem: This theorem states that the current or voltage at any pair of terminals in a linear network is the same when the terminals are interchanged.
Tellegen's theorem: This theorem states that the sum of the products of branch currents and voltages in a closed network is zero.
Topology
Topology is the study of the properties and relations of geometric figures that remain unchanged under certain transformations. In network analysis, topology refers to the arrangement and interconnection of network elements. Some of the concepts and terms related to topology are:
Graph: A graph is a representation of a network using nodes and branches. Nodes are points where two or more branches meet, and branches are lines connecting nodes.
Tree: A tree is a graph that has no closed loops or cycles. A tree contains n-1 branches for n nodes.
Cut-set: A cut-set is a set of branches that divides a graph into two parts when removed.
Tie-set: A tie-set is a set of branches that forms a closed loop in a graph.
Incidence matrix: An incidence matrix is a matrix that shows the relation between nodes and branches in a graph. Each row represents a node and each column represents a branch. The elements are +1, -1 or 0 depending on whether the branch enters, leaves or does not touch the node.
Kirchhoff's laws: Kirchhoff's laws are two basic laws that govern electric circuits. Kirchhoff's current law (KCL) states that the algebraic sum of currents at any node is zero. Kirchhoff's voltage law (KVL) states that the algebraic sum of voltages around any closed loop is zero. aa16f39245
