From this we can see that the larger the applied voltage, the larger the
current, while the larger the resistance, the smaller the current.

In the previous chapter we examined the interrelation
of current, voltage, resistance, and power in a single
resistor circuit.
In this chapter we will expand on these basic concepts

The Series-Parallel Network
In electric circuits,we define a branch as any
portion of a circuit which can be simplified as
having two terminals.
The components between the two terminals
may be any com
