In the circuit of Problem 88, at what time after switch S is closed is the voltage across the combination of three capacitors 50% of its final value?

Data From Problem 88

Consider the circuit shown withR₁ = 25 Ω, R₂ = 33 Ω, C₁ = 12 μF, C₂ = 23 μF, C₃ = 46 μF, 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?
