A 15-?F air-filled capacitor is connected to a 50-V voltage source and becomes fully charged. The voltage source is then removed and a slab of dielectric that completely fills the space between the plates is inserted
The dielectric has a dielectric constant of 5.0. (a) What is the capacitance of the capacitor after the slab has been inserted? (b) What is the potential difference across the plates of the capacitor after the slab has been inserted? What will be an ideal response?
A charged capacitor is connected to an ideal inductor to form an LC circuit with a frequency of oscillation f = 1.6 Hz. At time t = 0 the capacitor is fully charged
