Why do the two plates of a capacitor store equal amounts of charge?
If your capacitor starts out uncharged, then unless you add or remove charge to it, it will always remain net neutral. Charging a capacitor simply applies a voltage to both sides
Suppose two parallel-plate capacitors have the same charge Q,
Charge on a capacitor. Amount of charge a capacitor can hold is equal to the product of capacitance and potential difference across terminals of the capacitor. if two capacitors are

Do capacitors in series have the same charge?
Flexi Says: Yes, capacitors connected in series have the same charge. The charge stored on one plate of a capacitor must be equal to the charge stored on the opposite plate of the next
Charge distribution on capacitors connected in series
Since capacitors in series all have the same current flowing through them, each capacitor will store the same amount of electrical charge, Q, on its plates regardless of its
Why does the distance between the plates of a capacitor affect its
Intuitive approach: if the distance wouldn''t be a factor then you would be able to place the plates at an infinite distance apart and still have the same capacitance. That doesn''t
How does charge redistribute in a capacitor?
Capacitor plates that are parallel and of the same size will have equal and opposite charge. But for there to be unequal charge on two capacitor plates there needs to be
Capacitors in Series & Parallel | Formula & Examples
Capacitors in parallel have the same voltage across their plates but have different charge on each plate. Capacitors in series each store the same amount of charge but
The charge and discharge of a capacitor
Now, if a hole is made in the bottom of the bucket the water will run out. Similarly, if the capacitor plates are connected together via an external resistor, electrons will flow round the circuit,
electric circuits
So under what conditions the two capacitors in series have same charge, both uncharged at first? The problem is from the book, electricity and magnetism by Purcell chapter
Why is charge the same on every capacitor in series?
In the normal case, this means that if charge flows out one lead it must flow into the lead of another capacitor (the voltage source obeys KCL) so all the capacitors must have equal charge. In the non-ideal case, of course,
Capacitance and Charge on a Capacitors Plates
Charging a capacitor simply applies a voltage to both sides (i.e. it doesn''t add or remove charge), so the capacitor must remain net neutral. In other words, the two plates must
If the plates of a capacitor have different areas, will they
In the case of connecting a capacitor which plates have different areas across a battery, the voltage across both of the plates will be the same. Since the charge stored on the plates is

Why the charge is the same for capacitors connected
Is there any justification that plate 2 must have the same charge as plate 1? In a series circuit the current (charge per unit time) is the same going through all components. That means at any instant in time the positive charge

How do we know that both plates of a capacitor have the same

6 FAQs about [Capacitor plates have the same charge]
How do capacitors store different amounts of charge?
Capacitors with different physical characteristics (such as shape and size of their plates) store different amounts of charge for the same applied voltage V across their plates. The capacitance C of a capacitor is defined as the ratio of the maximum charge Q that can be stored in a capacitor to the applied voltage V across its plates.
How many plates can a capacitor have?
Two capacitors in series can be considered as 3 plates. The two outer plates will have equal charge, but the inner plate will have charge equal to the sum of the two outer plates. For various practical reasons, you would probably want resistors in parallel to help balance the DC charge on the capacitors.
Why does a capacitor have a higher capacitance than a plate?
Also, because capacitors store the energy of the electrons in the form of an electrical charge on the plates the larger the plates and/or smaller their separation the greater will be the charge that the capacitor holds for any given voltage across its plates. In other words, larger plates, smaller distance, more capacitance.
What happens if a capacitor is placed on two sides?
As a result, once charge is placed on the two sides of an ideal capacitor there is no path which would allow for changes in the charge, except for the leads. In the normal case, this means that if charge flows out one lead it must flow into the lead of another capacitor (the voltage source obeys KCL) so all the capacitors must have equal charge.
Do capacitor plates have a total charge?
As the capacitor plates have equal amounts of charge of the opposite sign, the total charge is actually zero. However, because the charges are separated they have energy and can do work when they are brought together. One farad is a very large value of capacitance.
Can two capacitors in series be considered as 3 plates?
In the non-ideal case, of course, this does not apply. Two capacitors in series can be considered as 3 plates. The two outer plates will have equal charge, but the inner plate will have charge equal to the sum of the two outer plates.
