6 FAQs about [Capacitor charging and discharging detection]
What is capacitor charge?
capacitor is equal to the potential difference across the battery. Because the current changes throughout charging, the rate of flow of charge will not be linear.At the start, the current will be at its highest but will graduall decrease to zero. The following graphs summarise capacitor charge. The potential diffe
How do you discharge a capacitor?
To discharge It completely, short it with a wire. Prepare the rest of the circuit and, remove this wire as one of the last operations. Make sure the switch is off and build the circuit as shown on the drawing. Remember to remove the wire that shorts the capacitor. Start the stopwatch and turn the switch on simultaneously.
How to check if a capacitor is discharged through a resistor?
When we in a while turn the switch off, the capacitor will discharge through the resistor R . Read the initial voltage U0 precisely. Start the stopwatch and turn the switch off simultaneously. For every 10 seconds, you must read the voltage as precisely as possible – it will drop quite fast initially.
How is energy dissipated in charging a capacitor?

Connect both a voltage sensor and current sensor to a data logger. The stopwatch is no longer needed as the data logger has an internal timer.
How do you know if a capacitor is fully discharged?
Switch the switch to the opposite position and start the stop clock. the capacitor has fully discharged. Plot a graph of voltage against time for the discharging of the capacitor, and use it to determine the time constant of the capacitor.
