Problem

Two resistors of

2.0\,\text{k}\Omega

and

3.0\,\text{k}\Omega

are connected in parallel and placed in series with a network of two capacitors,

6.0\,\mu\text{F}

and

12\,\mu\text{F}

, that are connected in series. The combined resistor-capacitor assembly is then attached to a battery through a switch. What is the time constant of this circuit? (a)

18\,\text{ms}

(b)

4.8\,\text{ms}

(c)

1.2\,\text{ms}

(d)

29\,\text{ms}
