Say there are two parallel plates separated by a small fixed distance d and charged +q, -q. The force attracting the plates is F. If a solid block of dielectric (dielectric constant k) is introduced between the plates, will the force of attraction be different from F.
My answer: The electric...
Homework Statement
a) State the boundary conditions for the electric field strength E and electric flux density D at a planar interface separating two media with dielectric constants ε1 and ε2.
b) A parallel plate capacitor with a plate separation d is filled with two layers of different...
Hello all
I need a high K material to cancel out E-field in some direction (induced by electromagnetism). This high K material (above 5000) must work in high frequencies above 10MHz. I did use the ceramics but there is no clue that it will work in that range of frequencies or not.
I am really...
Homework Statement
A parallel-plate capacitor is connected to a 100 V battery until it is fully charged. The distance between the plates is d and the space between the plates is filled with air (k=1.0). Then, the battery is disconnected. If the distance between the plates is increased to 3d...
Hallo,
I have a question which elements are responsible for the increase of tangent delta in a X Capacitor and the reduction of its insulation resistance?
suppose i have a circuit,in which a capacitor and resistances are connected in series with a DC voltage source.
then after a long interval of time we know that capacitor will have same voltage across its terminal as that of DC voltage source and no current flow in the circuit.
so, can i say at...
