Chapter 5 Capacitance and Dielectrics
The force between the plates of a charged capacitor is $$F=QE$$ Where $Q$ is the net charge on each capacitor plate and $E$ is the electric field between the …
Chapter 5 Capacitance and Dielectrics
0 parallelplate Q A C |V| d ε == ∆ (5.2.4) Note that C depends only on the geometric factors A and d.The capacitance C increases linearly with the area A since for a given potential difference ∆V, a bigger plate can hold more charge. On the other hand, C is inversely proportional to d, the distance of ...
Assertion and Reason Questions on Class 12 Physics Chapter 2 Electrostatic Potential and Capacitance
Q.2. Assertion : A parallel plate capacitor is connected across battery through a key. A dielectric slab of dielectric constant K is introduced between the plates. The energy which is stored becomes K times. Reason : The surface density of charge on the plate remains constant or unchanged. ...
Capacitors and dielectric
Answer: (i) As the capacitor is isolated after charging, hence the charge Q on the plates remains unchanged. ii) Capacitance is indirectly proportional to the distance d between the plates. iii) As Q = CV, and Q is constant here, hence as C increases Potential

An air capacitor C connected to a battery of e.m.f. V acquires a charge q and energy E. The capacitor …
Statement 1: A parallel plate capacitor is charged by a battery of voltage V.The battery is then disconnected. If the space between the plates is filled with a dielectric, the energy stored in the capacitor will decrease. Statement 2: The capacitance of a capacitor increases due to the introduction of a dielectric between the plates.
8.1 Capacitors and Capacitance
In fact, this is true not only for a parallel-plate capacitor, but for all capacitors: The capacitance is independent of Q or V. If the charge changes, the potential changes …
Why does the distance between the plates of a …
As Capacitance C = q/V, C varies with q if V remains the same (connected to a fixed potential elec source). So, with decreased distance q increases, and so C increases. Remember, that for any …
Why does the voltage increase when capacitor plates are …
When you increase the distance between electrodes - capacitance drops, but stored charge remains the same, as electrons have nowhere to go. Same …
