Capacitors and RC Circuits v 0.3circuit elements such as resistors. In a series combination there is only one path for the flowof electric charge, and whatever charge is placed on one capacitor must also be transferred tothe other. In a parallel connection, the two terminals of each capacitor are connected to theterminals of the other. While each capacitor has the same potential difference across it, eachconstitutes a branch so that the total charge transferred to the capacitor combination is splitamong the two capacitors.C 1C 1C 2C 2C 1C 1 C 2C 2(a) Capacitors in Series(b) Capacitors in parallelFigure 4: Capacitors wired in (a) series and (b) parallelTo examine the equivalent capacitance of two capacitors connected in series or in parallelyou will need:• 2 capacitors, on the order of 0.1µF• 1 multimeter with capacitance range.• Pasco circuit board• connecting wires.Pasco Circuit Board:PHYS-204:Physics II Laboratory 7
