The capacitor charges when connected to terminal P and discharges when connected to terminal Q. At the start of discharge, the current is large (but in the opposite direction to when it was charging) and gradually falls to zero. As a capacitor discharges, the current, p.d and charge all decrease exponentially. This means the rate at which the current, p.d or charge

6 FAQs about [Capacitor charging and discharging regulations]
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
What happens when a capacitor is fully discharged?
(Figure 4). As charge flows from one plate to the other through the resistor the charge is neutralised and so the current falls and the rate of decrease of potential difference also falls. Eventually the charge on the plates is zero and the current and potential difference are also zero - the capacitor is fully discharged.
What happens if a capacitor Harges?
harges, electrons flow onto one plate and move off the other plate. This process will be continued until the potential difference across th 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
How does capacitor charge change during charging?
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 ence and charge graphs look the same because they are proportional.You can also see that the gra
How do you charge a capacitor with a data logger?
charging began (s), R is the resistance of the fixed resistor and C is the capacitance of the capacitor. 0 the initial current. The area under the I-t graph gives the charge stored by the 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 long does it take to discharge a capacitor?
Capacitors can still retain charge after power is removed which could cause an electric shock. These should be fully discharged and removed after a few minutes A student investigates the relationship between the potential difference and the time it takes to discharge a capacitor. They obtain the following results:
