Abstract (4) In this experiment, several circuits were constructed to find the capacitance of different capacitors. Using the science workshop, we found the different voltages running through the resistors at different times. The readings of the time and voltage were considered using the Data Studio. These readings were categorized into, C1 charging, C1 discharging, C1 and C2 Parallel discharging, C1 and C2 Series discharging. These results were then employed to calculate the charge and time intervals. The experimental values for C1 charging and discharging of 137.5±0.7 ( F) compared closely to the theoretical value of 117±15.9 ( F). The graph μ μ of Capacitor Charge vs. Time was exponential and hence proved the experiment.
