We begin by introducing steady-state electric circuits and the concept of a constant rate of flow of electric charges, known as direct current (dc) . We also introduce Kirchhoff’s two rules , which are used to simplify and analyze more complicated circuits. Finally, we consider circuits containing resistors and capacitors, in which currents can vary with time.enCopper WireInternal ResistanceLight BulbTerminal VoltageSilver WireElectric CircuitsBook chapterhttps://doi.org/10.1007/978-3-642-23026-4_24
