An air-filled parallel plate capacitor with a plate spacing of 1.20 cm has a capacitance of 3.40 �F. The plate spacing is now doubled and a dielectric is inserted, completely filling the space between the plates. As a result the capcitance becomes 15.4 �F. Calculate the dielectric constant of the inserted material.
An air-filled parallel plate capacitor with a plate spacing of 1.90 cm has a capacitance of 4.10 μF. The plate spacing is now doubled and a dielectric is inserted, completely filling the space between the plates. As a result the capacitance becomes 16.9 μF. Calculate the dielectric constant of the inserted material.
A parallel plate capacitor of capacitance C0 has plates of area A with separation d between them. When it is connected to a battery of voltage V0, it has charge of magnitude Q0 on its plates. The plates are pulled apart to a separation 2d while the capacitor remains connected to the battery and the space between the plates is filled halfway with a material having the dielectric constant K. What are the capacitance and the magnitude of the charge...
