When an empty (discharged) capacitor is connected to a battery, it slowly charges up as one plate fills up with electrons, while the other plate has electrons drawn away from it towards the positive terminal of the battery, resulting in one plate having a positive charge and the other having a negative charge.
The same ideas also apply to charging the capacitor. During charging electrons flow from the negative terminal of the power supply to one plate of the capacitor and from the other plate to the positive terminal of the power supply.
A capacitor can take a shorter time than a battery to charge up and it can release all the energy very quickly. How much can we charge? When connected to a cell or other power supply, electrons will flow from the negative end of the terminal and build up on one plate of the capacitor.
When a voltage is placed across the capacitor the potential cannot rise to the applied value instantaneously. As the charge on the terminals builds up to its final value it tends to repel the addition of further charge. (b) the resistance of the circuit through which it is being charged or is discharging.
When you turn on the power, an electric charge gradually builds up on the plates. One plate gains a positive charge and the other plate gains an equal and opposite (negative) charge. If you disconnect the power, the capacitor keeps hold of its charge (though it may slowly leak away over time).
That post improved quite significantly! The electrons don't actually pass through the capacitor. As one plate of a capacitor gains electrons, that creates an electric field that repels the electrons of the other plate, and it's those electrons that go on to move through the stuff on the other side of the capacitor.
Once the battery is removed, if there''s some closed loop path between the plates of the capacitor, then the excess charge on one side of the capacitor will use the closed loop to balance out the …

The resulting electric field causes negative charges to move away from the opposite face of the capacitor, leaving it with a net positive charge. This charge redistribution creates a voltage in …
During charging electrons flow from the negative terminal of the power supply to one plate of the capacitor and from the other plate to the positive terminal of the power supply. When the switch is closed, and charging starts, the rate of flow …
On these plates, as the capacitor is charged up and the voltage across the plates goes up, positive and negative charges will collect on the different plates. Capacitor …
The capacitor is initially uncharged. When the switch is moved to position (1), electrons move from the negative terminal of the supply to the lower plate of the capacitor.
The electron current will flow out the negative end of the battery as usual (conventional current will exit the positive end). Positive charges begin to build up on the right plate and negative charges on the left. The electric field …
Once the battery is removed, if there''s some closed loop path between the plates of the capacitor, then the excess charge on one side of the capacitor will use the closed loop to balance out the charge. Excess electrons from the negative …
When connected to a cell or other power supply, electrons will flow from the negative end of the terminal and build up on one plate of the capacitor. The other plate will have a net positive charge as electrons are lost to the battery, …
When current flows into a capacitor, the charges get "stuck" on the plates because they can''t get past the empty space between the plates directly. ... The large mass of …
