A parallel plate capacitor is made of two parallel disks of metal separaded by a gap. The radius of the disk is 2.0m, the distance between the plates .25m.
A) What is the capacitance of the above capacitor?
B) This capacitor is connected to a 12v voltage source. How much charge can be stored in the capacitor?
C) What is the energy stored in the capacitor?
D) A glass slide with the dielectric constant 4.5 is inserted between the plates completely filling the space inside of the capacitor.Find the capacitance after adding the dielectric.
