Capacitors in Circuits 10/23

Today we learned that a capacitor is a device that stores electric charge and electric potential energy.
We defined capacitance as the measure of the ability of a device to store charge per unit of voltage applied across the device
C=Q/V

we learned that for capacitor in series the charge is conserved and that capacitors in parallel have the same voltage drop across one another.
we also proved theoretically by using the definition of current flow and relating it to capacitance that qc= q0 e(-t/RC), and V=Vo e^(-t/rc)
Here we have applied a best fit to the graph and shown experimentally the rate at which capacitors discharge and charge. Where the constant C is equal to 1/rc.
