the telegan law basically states that the total sum of power is zero.
my prof proved lik this:
we choose a node (a point where more then one currents come together)
and decide that the voltage on that node to be zero.
we designate the voltages on the nodes to be
is the current.
is the number of nodes.[/tex]
is the number of branches.[/tex]
each J that does not exist in the graph will be zero.
because by kcl
my problem iswhen he sums for all nodes
sign which by me represents multiplication
of the sums
why not ,thus we can know that ist the sum of many similar equations.
but how he did it doesnt represent a sum
