A parallel plate capacitor is made of plates of area 0.05 m? each. The plates are separated by a distance of 0.200 mm. Initially, the space between the plates is filled with air. (a) What is the capacitance of this air-filled capacitor? (b) If the electric field inside the capacitor exceeds 3.00 x 106 V/m, the air undergoes electrical break- down. (This maximum field is known as the dielectric strength of air.) From this, calculate the maxi- mum voltage (potential...

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 uncharged parallel-plate capacitor with only air between the plates has C◦ = 0.600 mF. It is connected to an EMF source with E = 6.00 V. a) How much charge Q◦ accumulates on the cap, and how much energy is stored, U◦? b) The capacitor is discharged back to zero, then filled with a dielectric material that brings its capacitance up to C1 = 1.950 mF. What is the value of κ1 for the dielectric material? When connected to...

A parallel plate capacitor of capacitance C0 has plates of area A with separation d between them.
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. While it is connected to the battery the space between the plates is filled with a material of dielectric constant k=3. After the dielectric is added, the magnitude of the charge on the plates and the new capacitance are
