The product of Resistance R and Capacitance C is called the Time Constant τ, which characterizes the rate of charging and discharging of a Capacitor, Figure 5. Figure 3: The Capacitor is charging. Figure 4: The Capacitor is discharging. The current and the charge are exponential functions of time as follows: 𝑖 = 𝐼 0 𝑒− 𝑡𝑅𝐶 (2)
Some capacitors, called electrolytic capacitors, respond badly (i.e. they can explode) if they are charged incorrectly. It matters which way round the terminals of the capacitor are connected
1. Set up the circuit as shown in the diagram. 2. Close the switch to charge the capacitor, record the voltage and current at time t = 0 and at 5 s intervals as the capacitor charges until about 120s have passed. This may be made easier by working in pairs. 3. Repeat the experiment twice more and record the voltage and current for each time again.
The capacitor will discharge a bit from the 470R resistor, but normally that would only be during the dead time when both MOSFETs are off. It would also discharge a bit in charging the

The Capacitor Charge Current Calculator is an essential tool for engineers, technicians, and students who work with capacitors in electrical circuits. This calculator determines the charging current required to change
Using a resistor with too low a resistance will not only mean the capacitor discharges too quickly but also that the wires will become very hot due to the high current. Capacitors can still retain charge after power is removed
Core Practical 11: Use an oscilloscope or data logger to display and analyse the potential difference (p.d.) across a capacitor as it charges and discharges through a resistor
When current-time graphs are plotted, you should remember that current can change direction and will flow one way on charging the capacitor and in the other direction when the capacitor is discharging.
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

Ans: During the process of charging the capacitor, the current flows towards the positive plate (and positive charge gets added to that plate) and away from the negative plate. While during the discharging of the capacitor, current flows away from the positive and towards the negative plate, in the opposite direction.
Capacitor Charging and discharging is related to the charge. Capacitor charging means the accumulation of charge over the capacitor. Current Equation: The below

If the resistance is high, the current will decrease and charge will flow from the capacitor plates more slowly, meaning the capacitor will take longer to discharge

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 gradually decrease to zero. The following graphs summarise capacitor charge. The potential difference and charge graphs look the same because they are proportional.
The size of the current is always at a maximum immediately after the switch is closed in the charging or discharging circuit, because the charging current will be highest when the capacitor is empty of charge, and the discharging current will be highest when the capacitor is full of charge. This is shown in the graphs in Figure 2. 2.
Graphs of V (the p.d. across the capacitor) against t follow the same pattern as the graph of Q against t, because Q ∝ V (from Q = VC). When current-time graphs are plotted, you should remember that current can change direction and will flow one way on charging the capacitor and in the other direction when the capacitor is discharging.
As more charge is stored on the capacitor, so the gradient (and therefore the current) drops, until the capacitor is fully charged and the gradient is zero. As the capacitor discharges (Figure 3 (b)), the amount of charge is initially at a maximum, as is the gradient (or current). The amount of charge then drops, as does the gradient of the graph.
