A parallel plate capacitor with vacuum between its plates has capacitance C. A slab of dielectric constant K and having the same thickness as the separation between the plates is introduced so as to fill 1/3rd of the capacitor as shown in the figure. the new capacitance will be Minimum number of capacitors of 4μF [...]

A parallel plate capacitor with air between the plates has capacitance of 9pF. The separation between its plates is ‘d’. The space between the plates is now filled with two dielectrics. One of the dielectrics has dielectric constant k1=3 and thickness d3 while the other one has dielectric constant k2=6 and thickness 2d/3. Capacitance of [...]
