RC-Circuit
Connecting Logger Pro withe the circuit which include power supply, capacitor, and resistor in series to measure the change of voltage over time across the capacitor(discharging).
Connecting Logger Pro withe the circuit which include power supply, capacitor, and resistor in parallel to measure the change of voltage over time across the capacitor(charging).
The graph of voltage vs time in the capacitor.
The blue curve show the changes of voltage when the capacitor is charging.
The red curve show the changes of voltage when the capacitor is discharging.
Base on the experiment data we can say the B value in the natural exponential equation should be fairly close to 0. We also can say that the A value should be the original 4.5 Voltage which from the power supply. Finally, the C value should relate to the capacitance and resistance.
