Capacitor and battery curve
When a capacitor charges, electrons flow onto one plate and move off the other plate. This process will be continued until the potential difference across the 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. When a capacitor is discharged, the current will be highest at the start. This will gradually decrease until reaching 0, when the current reaches zero, the capacitor is fully discharged as there is. The rate at which a capacitor charges or discharges will depend on the resistance of the circuit. Resistance reduces the current which can flow. The time constant we have used above can be used to make the equations we need for the discharge of a capacitor. A general equation for exponential decay is: For the equation of capacitor discharge, we put in the time. The time constant is the time it takes for the charge on a capacitor to decrease to (about 37%). The two factors which affect the rate at which charge flows are resistance and capacitance. This means that the following equation.

Do non polarized capacitors have a positive or negative terminal?
Non-polarized capacitors do not have a positive or negative terminal and can be connected to a circuit in any polarity. For optimal performance, you must orient polarized capacitors in the correct direction since they have positive and negative terminals, making them essential components.
What determines the polarity of a capacitor?
The orientation of the electric field dictates polarity. The positive plate accumulates positive charges, while the negative plate accumulates negative charges, creating an electric potential difference across the capacitor for energy storage and release in circuits.
