Two parallel - plate capacitors A and B are connected in series.Capacitor A has a plate area of 5000 mm?.an air dielectric and the distance between the plates is 1 mm.Capacitor B has a plate area of 2000 mm² , a solid dielectric of relative permittivity 4 and of thickness 0.5 mm.Find the voltage across the combination if potential grandient associated with capacitor A is 100 kV / m.

What is a dielectric material, and what does it do? a. What are 3 ways capacitance can be increased by changing the materials?

An initially uncharged parallel plate capacitor is connected to a circuit containing a battery with emf -15V and a resistor, R = 8.5MN as shown in the figure to below. The capacitor whose plates have an area of A = 3.1mm² are separated by a distance of d = 3.4mm and one third of the capacitor is filled with a dielectric material, K₁= 1.1 and the rest (two thirds) is filled with another dielectric material, K₂=4.5. At t=0 the switch is closed. 7.1 seconds after the switch is closed the electric field within the first dielectric material (₁) is observed to be 15 x 10³ N/C. Find the potential difference across the capacitor at this instant (t = 7.1 s) in terms of permitivity of free space €0? Express your answer using zero decimal place. R S K₁ K₂
