KIRCHOFF’S VOLTAGE LAW: KVL is based on the law of the law of conservation of the energy, states that the algebraic sum of voltage drops in a closed loop is zero.{Flow of currents in loop is assumed +ve from higher potential to lower potential in elements and +ve from lower to higher potential in Sources}.
NODES, BRANCHES AND LOOPS:
Network is an interconnection of elements or devices, circuit is a network providing one or more closed paths
A BRANCH represents a single element such as voltage source or a resistor.
A NODE is the point of connection of two or more branches.
A LOOP is any closed path in a circuit. A network with ‘b’ branches, ‘l’ loops and ‘n’ nodes should satisfy the theorem of n/w topology.(b =l +n – 1).
SERIES ELEMENTS AND VOLTAGE DIVISION Two or more elements are in series if they are cascaded or connected sequentially and consequently carry the same current. The equivalent resistances of any number of resistors connected in series is the sum of the individual resistances.
DEPENDENT OR CONTROLLED SOURCES: In some network, in which some of the voltage sources or current sources are controlled by changing of current or voltage elsewhere in the circuit. Such sources are termed as “Dependent or Controlled sources”. There are four types of dependent sources.i.CDVS( Current DVS), ii.CDCS(Current DCS) ,iii.VDVS(Voltage DVS) iv.VDCS(Voltage DCS).
SOURCE TRANSFORMATION: A practical voltage source can be replaced by a current source and vice versa. This can be established if an equivalence between a voltage source and a current source.
Very informative..good work
