It consists of two parallel metal plates of area 250 cm2. A sheet of polythene that has a relative permittivity 2.3 completely fills the gap ... €€€€ The capacitor is charged so that there is a …
Why does the distance between the plates of a capacitor affect …
If the capacitor is charged to a certain voltage the two plates hold charge carriers of opposite charge. Opposite charges attract each other, creating an electric field, and the …
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 …
Charged Capacitor
A capacitor is when two uniformly, but oppositely (-Q and +Q), charged metal plates are held very close to each other with a separation of s which stores electric charge. …
What is the electric field in a parallel plate capacitor?
When we find the electric field between the plates of a parallel plate capacitor we assume that the electric field from both plates is $${bf E}=frac{sigma}{2epsilon_0}hat{n.}$$ The factor of two …
Capacitance and Charge on a Capacitors Plates
Capacitance is the electrical property of a capacitor and is the measure of a capacitors ability to store an electrical charge onto its two plates with the unit of capacitance being the Farad (abbreviated to F) named after the British …

Example 5.1: Parallel-Plate Capacitor Consider two metallic plates of equal area A separated by a distance d, as shown in Figure 5.2.1 below. The top plate carries a charge +Q while the …
Why do both plates of a capacitor have the same …
How do we know that both plates of a capacitor have the same charge? You could argue conservation of charge, but I don''t see how conservation of charge implies the charge on both plates is the same. Say you have a charge of +q …
