Electric Circuits

Abstract

In this chapter we analyze simple electric circuits that contain devices such as batteries, resistors, and capacitors in various combinations. 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.
