The plates of the capacitor have an area of 1.24x 10-4 m2 . They are separated by a distance of 6.50 µm by a material with a dielectric constant. A 25 V battery is used to begin charging. After a long time, the capacitor is fully charged to 465 nC. a) What is the dielectric constant of the material? An 8200 Ω resistor is made of a material with a resistivity of 55.9 Ω m, and a length of 1.40 m. b) What is the cross-sectional area of the resistor? The charged capacitor from part a) is disconnected from the battery and placed in series with the resistor from part b), creating an RC circuit, allowing the capacitor to discharge. c) What is the initial current in the circuit when the capacitor first starts discharging? d) How much charge is left on the capacitor after 3 time constants have elapsed?
