The electron current will continue to flow and the electric field will continue to exist until the potential difference across the capacitor is equal to that of the batteries (sum of emf of all bat.

This means more current must flow to transfer the same usable power, leading to wasted energy. Capacitors counteract these inductive loads by providing reactive power.

AI Customer ServiceIn theory it will. If an ideal capacitor is charged to a voltage and is disconnected it will hold it's charge. In practice a capacitor has all kinds of non-ideal properties. Capacitors have 'leakage resistors'; you can picture them as a very high ohmic resistor (mega ohm's) parallel to the capacitor.
V = IR, The larger the resistance the smaller the current. V = I R E = (Q / A) / ε 0 C = Q / V = ε 0 A / s V = (Q / A) s / ε 0 The following graphs depict how current and charge within charging and discharging capacitors change over time. When the capacitor begins to charge or discharge, current runs through the circuit.
However, so long as the electron current is running, the capacitor is being discharged. The electron current is moving negative charges away from the negatively charged plate and towards the positively charged plate. Once the charges even out or are neutralized the electric field will cease to exist. Therefore the current stops running.
Capacitors will lose their charge over time, and especially aluminium electrolyts do have some leakage. Even a low-leakage type, like this one will lose 1V in just 20s (1000 μ μ F/25V). Nevertheless, YMMV, and you will see capacitors which can hold their charge for several months. It's wise to discharge them.
When capacitors in series are connected to a voltage supply: because the applied potential difference is shared by the capacitors, the total charge stored is less than the charge that would be stored by any one of the capacitors connected individually to the voltage supply. The effect of adding capacitors in series is to reduce the capacitance.
Yes, the capacitor voltage will fall as current is drawn from it, so you must initially charge the capacitor to a higher voltage than you need and then draw current from it until it reaches the lowest voltage you can still use. Also is the capacitor voltage drop linear to its capacity? for example a 5v charged capacitor when at 50% is 2.5v?
