3.1: Moving Charge
We begin with some mathematical tools for dealing with moving charge, keeping in mind the observed physical law that charge is neither created nor destroyed.
3.2: Resistance and Energy Dissipation
We now discard our assumption from electrostatics that conductors allow totally free (instantaneous) movement of electric charge, and take into account the effects of "electrical friction."
3.3: Networks of Batteries and Resistors
We can employ analysis similar to what we used in static circuits to circuits that contain electric current passing through resistors, though it requires a twist to the notion of potential difference used in the static case.
3.4: Kirchhoff's Rules
Not every conceivable circuit can be analyzed using the tools of the previous section. Here we learn some tools that can be used in more general cases.
3.5: RC Circuits
Up to now, we have only considered the role of capacitors under static circumstances. We now incorporate them into our moving-charge networks.
