Question
I only need the answer to subpart G.
15. Two circular disks with radius 13.5 cm are placed 0.750 mm apart What is its capacitance if a piece of paper (k -3.7) were in between the plates? a. b. If placed in a circuit wit each plate? h a 9.00 V potential generator, how much charge would be built up on C. h 8.95 V of This is charged in series with a 35.0 kn resistor, how long does it take to reac potential? c. 2 sesovol d. How much energy is stored in the capacitor, when it is fully charged? e. How much energy density is stored in the Electric field between the plat 1 2. f. While in the circuit, remove the dielectric, find the energy stored in the Capacitor now? 15 J g. Instead of part F, remove the capacitor from the circuit, then take the dielectric out, find the energy stored in the Capacitor now?Explanation / Answer
The answer of Part "g" will be same as Part "d".
Because in this part we removed the fully charged capacitor (which has the dielectric material) from the circuit and after removing we sperated the dielectric from capacitance so the total enegry will be as-
E = Q2/2C where Q is charge on capacitor. and that charge will not change after removing the dielectric.
