A 20-ohm resistor and a capacitor are connected in series with a battery of 60 volts. At t = 0, there is no charge on the capacitor. Find the capacitance if the current at t = 5 seconds is 3/e^s amperes.
Ans. 0.05 Farads
1) First part of the question: Two identical capacitors are connected in
parallel and charged with a 20-V power supply as shown in the figure on
the left. After the charges on the capacitors have reached their final values,
the charge on each capacitor is 10 µC. Then the power supply is
disconnected and a dielectric with K = 4 is inserted to fill the space
between the plates of one of the capacitors. a) Find now the charge on the
capacitor with dielectric. Give your answer in microcoulombs.

A capacitor is made of 2 rectangular metal plates with side length of 3 cm x 6 cm separated by a distance of 2.36 cm with water in between the plates. The capacitor has a voltage of 110 v and is not connected to a battery. Calculate the capacitance. What is the new capacitance if we replace water with a new dielectric material with a constant of 3.75 in between the plates? What is the new voltage? What is the charge on each plate?
