flows out of the terminal at which the positive of the voltage
source is presently connected.
• An n-node circuit containing only linear resistors and inde-
pendent current sources will have a nodal representation
given by YV CU, where Y is the nodal conductance matrix
of order (n 1) (n
1), V is the node voltage column
vector of order (n
1) 1, U is the source current column
vector of order n
cs
1 and C is the input matrix of order
(n

cs
. n
cs
is the number of independent current
sources in the circuit. CU may be replaced by a column vec-
tor which contains the net current delivered to a node by all
independent current sources connected ...
