An RC Circuit Consists of a Resistor with Resistance 1 $\varOmega$

question 38

Multiple Choice

An RC circuit consists of a resistor with resistance 1.0 k $\varOmega$ , a 120-V battery, and two capacitors, C1 and C2, with capacitances of 20.0 µF and 60.0 µF, respectively. Initially, the capacitors are uncharged; and the switch is closed at t = 0 s.
-Determine the total charge on both capacitors two time constants after the switch is closed.
