Changing Capacitance Yields a Current Each plate of a parallel-plate capacator is a square with side length r, and the plates are separated by a distance d. The capacitor is connected to a source of voltage V. A plastic slab of thickness d and dielectric constant K is inserted slowly between the plates over the time period At until the slab is squarely between the plates. While the slab is being inserted, a current runs through the battery/capacitor circuit. (Figure...

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.

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.

Capacitor A is a standard parallel-plate capacitor with
no dielectric. It was charged up (though is currently not attached
to anything) and currently has charge of Qo, a voltage
of Vo, a capacitance of Co, and a potential
energy of PEo. A dielectric with K = 67 is to be
inserted into capacitor A. Determine what the capacitance, charge,
voltage, & potential energy of capacitor A will be once the
dielectric is fully inserted.
