A number of electrical laws apply to all electrical networks. These include

*[[Kirchhoff's circuit laws#Kirchhoff's current law|Kirchhoff's current law]]: the sum of all currents entering a node is equal to the sum of all currents leaving the node.

*[[Kirchhoff's circuit laws#Kirchhoff's voltage law|Kirchhoff's voltage law]]: the directed sum of the electrical potential differences around a circuit must be zero.
