Besides demonstrating the charging and discharging process of capacitors, this circuit also gives beginners in electronics a hands-on understanding of the characteristic of capacitors to
Charging and Discharging Definition: Charging is the process of restoring a battery''s energy by reversing the discharge reactions, while discharging is the release of stored energy through
Getting Started with Your First Experiment: Cyclic Charge Discharge. The purpose of this test is to apply a constant current to batteries, super capacitors, or electrode materials in order to
When the current reference is positive, the converter works as a buck converter, charging the battery from the power source. When the current reference is negative, the converter works as

If we now connect the two plates of the capacitor with a wire or resistor, charge will ow from the negatively charged plate to the positively charged plate in an e ort to balance out the charge.
PDF version includes complete article with source references. Suitable for printing and offline reading.
The discharging circuit provides the same kind of changing capacitor voltage, except this time the voltage jumps to full battery voltage when the switch closes and slowly falls when the switch is opened. Experiment once again with different combinations of resistors and capacitors, making sure as always that the capacitor's polarity is correct.
Go into the Framework software and navigate to “Experiment”- “Electrochemical Energy”- “Cyclic Charge Discharge”. Page one of the experimental setup screen will open. See figure 2. Name your experiment identifier under base file name. Capacity in A-hr. If known, it can be entered here. An approximate value is suitable.
The diagram above shows a circuit that can demonstrate the process of charging and discharging capacitors. The charging circuit consists of S1, R1, a red LED, and electrolytic capacitors C1 and C2. The charging current is indicated by the red LED.
Brief Summary: From the analysis of the charging and discharging process of the capacitors above, we can intuitively feel that the charging and discharging time of the capacitors is related to the limiting resistors R1, R2 and the capacitors C1, C2.
