Day 17

Discharge and Charge of Capacitors

In this experiment, we intended to measure the relationship in the time it takes to charge and discharge a capacitor in an RC-Circuit.  The upper left of the picture above, the diagram in for the the RC-Circuit is displayed. An EMF of 4.5 V was exerted into the circuit which contained a 3.6 kilo ohm resister and capacitor.  The voltage in the system was measured with logger pro as a function of Voltage vs Time in both charging and discharging of the capacitor.  


The picture above displays the graphs of a charging capacitor in blue and a discharging capacitor in red.  It is determined through the curve fit line that the voltage is an exponential function, V=Voe^(1/torr).  It was determined earlier, in the previous picture, that for is equaled to R*C, the resistance times the capacitance.  More importantly torr is a measurement in time of seconds.
