What is the minimum plate area, in squared meters, if the capacitor must withstand applied voltages up to 4.1 kV/m? Amin = m ,2

A parallel plate capacitor has the space between its plates filled with 1.4 mm of paper and 3.9 mm of teflon, as shown in the figure on the right. If the area of the plate of a capacitor is 9.2 cm², what is the capacitance of the capacitor? (Express your answer in pF (i.e. picofarads) Answer:

A parallel-plate capacitor initially has Quartz between its plates and carries charge ±Q. A different dielectric is then inserted between the plates without changing the charge. If the energy stored in the capacitor decreases to 72% of its initial value, what is the value of x for the new dielectric? K =

A 4 μF parallel-plate capacitor with a dielectric has a charge of 42 μC on each plate. The distance between the plates is 0.007 m and the dielectric constant is 153. Determine the area of each plate and the E-field between the plates. A = E =

When a 360-nF air capacitor is connected to a power supply, the energy stored in the capacitor is 15.6 μJ. While the capacitor is connected to the power supply, a slab of dielectric is inserted that completely fills the space between the plates. This increases the stored energy by 23.8 μJ. What is the dielectric constant of the slab?

A parallel-plate capacitor consists of two plates, each with an area of 25  cm2 separated by 3.0  mm . The charge on the capacitor is 4.8  nC . A proton is released from rest next to the positive plate. How long does it take for the proton to reach the negative plate? Express your answer with the appropriate units.

A parallel plate capacitor has capacitance C0 = 15.0 pF when there is air between the plates. The separation between the plates is 1.00 mm. A dielectic with K=3.50 is inserted between the plates of the capacitor, completely feeling the volume between the plates. The capacitor is connected with a battery. Find the magnitude of charge on each plate if the electric field between the plates is 3.00 x 104 V/m.
