Consider the circuit shown with R1 = 25 ?, R 2 = 33 ?,
C1 = 12 ?F, C2 = 23 ? F, C3 = 46 ?F, and V = 6.0 V.
(a) Draw an equivalent circuit with one resistor and one capacitor and label it with the values of the equivalent resistor and capacitor.
(b) A long time after switch S is closed, what are the charge on capacitor C1 and the current in resistor R1?
(c) What is the time constant of the circuit?
(d) At what time after switch S is closed is the voltage across the combination of three capacitors 50% of its final value?
