Capacitor Investigation Report Purpose: The purpose of this investigation is to study the charging and discharging of capacitors. A capacitor is charged by placing it in a circuit with a resistor and a power source. When electrons flow around the circuit they cannot cross the empty space created by the capacitor. On this side of the capacitor a negative charge accumulates while on the other side of the capacitor a positive charge accumulates. Now there is a potential difference across the range which causes charging to slow down. When the voltage across the gap is equal to the voltage of the power supply, there is no current since there is no voltage difference/potential difference and the capacitor is now fully charged. A capacitor can therefore be used in a circuit on its own without a power source. The charge on the capacitor gradually leaves it and discharges. Method: In this experiment we charged a 1000μF capacitor and then discharged it using two circuits. We studied the charging of capacitors using a voltmeter in parallel and a 10kΩ resistor in series. Every 5 seconds the voltage would drop, so we repeated this process but with the capacitor discharging. These were the circuits used: [IMAGE] And these were the results: time (s) charge (V) discharge (V) ln discharge (V)00102.3054.266.281.84106.244.241.44157.842.781.02208.91.980.68259.631.330.293010.140.96-0.043510.50.65-0.434010.720.46-0.784510.870.35-1.055010.990.
