Define dielectric constant.

A parallel plate capacitor is to be designed using a dielectric of dielectric constant 5, so as to have a dielectric strength of 10^(9) Vm^(-1) . If the voltage rating of the capacitor is 12 kV, the minimum area of each plate required to have a capacitance of 80 pF is .........

Define pole strength of magnet.

A parallel plate capacitor is to be designed with a voltage rating 1 kV, using a material of dielectric constant 3 and dielectric strength about 10^(7) Vm^(-1) . (Dielectric strength is the maximum electric field a material can tolerate without breakdown, i.e., without starting to conduct electricity through partial ionisation.) For safety, we should like the field never to exceed, say 10% of the dielectric strength. What minimum area of the plates is required to have a capacitance of 50 pF?

The dimensional formula of dielectric strength is…….

A parallel plate capacitor is made of two dielectric blocks in series. One of the blocks has thickness d_(1) and dielectric constant k_(1) and the other has thickness d_(2) and dielectric constant k_(2) as shown in figure. This arrangement can be thought as a dielectric slab of thickness d = ( d_(1) + d_(2) ) and effective dielectric constant k. The k is ...... (a) (K_(1)d_(1)+K_(2)d_(2))/(d_(1)+d_(2)) (b) (K_(1)d_(1)+K_(2)d_(2))/(K_(1)+K_(2)) (c) (K_(1)K_(2)(d_(1)+d_(2)))/((K_(1)d_(2)+K_(2)d_(1))) (d) (2K_(1)K_(2))/(K_(1)+K_(2))
