The functions of neurons and the nervous system can be understood through an analogy (the parallel conductance model) with electrical circuits. This chapter provides an introduction to the electrical terms and concepts that undergird this analogy. It begins with brief descriptions of the components that make up electrical circuits; namely, batteries, resistors, conductors, and capacitors. The basic quantities that describe these circuits are current, voltage, resistance, and capacitance. Ohm's law is introduced and together with Kirchhoff's rules, applied to electrical circuits constructed from the elemental components. Finally, equations that are fundamental for understanding the parallel conductance model and its relationship to cell membrane potentials are derived.

Keywords:   electricity, parallel conductance, resistor, conductor, capacitor, Ohm's law, current, Kirchhoff's rules
