The voltage and current dividor
Fondamental : Networks and dipoles
A network is a complex electrical circuit formed of conductive wire and components connected to the outside by two terminals (dipoles).
Dipoles may be placed in series :
Or in parallel (in derivation) :
Fondamental : Loop, branch and node
Node : a network node is an inter-connection point connected to at least three dipoles.
Branch : a branch is a circuit portion between two nodes. It can include one or more dipoles in series.
Loop : a loop is a set of branches, forming a closed loop, which passes only once by a given node.
Fondamental : Voltage Divider
The voltage divider is defined in the following figure :
Tensions and are expressed in terms of the voltage applied across the two resistors placed in series :
Fondamental : Current divider
The current divider is defined in the following figure :
Currents and are expressed in terms of current that arrives in the two resistances placed in parallel :
Conductances are given by :
