Types of Circuits © RHJansen Series One path All the electrical components are in a single line with only one path through them. Electricity has to flow through them in order. Parallel More than one path These are not necessarily visually parallel. The key is that there is more than one way for electricity to get from point A to point B . Electricity splits up between the available paths. Combination of Series and Parallel Part of the circuit is in series and part is in parallel.
Equivalent Capacitance © RHJansen When two or more capacitors are wired together the capacitance adds to form a sum of capacitance, or equivalent capacitance. The equivalent capacitance is the value of the capacitor that would be needed to do the same job as several capacitors added together. Adding Capacitors in Series Adding Capacitors in Parallel 1 C S = Σ 1 Χ ι 1 C S = 1 Χ 1 + 1 Χ 2 + 1 Χ 3 + ... C p = Σ Χ ι C p = Χ 1 + Χ 2 + Χ 3 + ...

Example 1 © RHJansen Solve for the equivalent capacitance 1 C S = Σ 1 Χ ι 1 C S = 1 2 + 1 4 C 1 = 2 F C 2 = 4 F There is only one path from left to right: Series 1 C S = 3 4 Be careful: we just solved for 1/ C . We are looking for C .
