A circuit consisting of resistors and capacitors is shown inFig.-1, below.E“120.0V,R1“4.00 MΩ,R2“8.00 MΩ,R3“2.50 MΩ,R4“1.50 MΩ,C1“15.0μF,C2“10.0μF,C3“7.00μF, andC4“3.50μF. The switch is initially open, and all capacitors are initially uncharged.
Figure 1 -E“120.0V,R1“4.00 MΩ,R2“8.00 MΩ,R3“2.50 MΩ,R4“1.50 MΩ,C1“15.0μF,C2“10.0μF,C3“7.00μF, andC4“3.50μF.
a)What will the charge on C4 be10.0 after the switch is closed?
b)What will the potential difference acrossC4 be10.0 after the switch is closed?
c)What will the current throughR4be10.0 after the switch is closed?
d)What will the potential difference across R4 be10.0 after the switch is closed?
e)The switch remains closed for a long time. But after the capacitors become fully charged, the switch is then opened. What will the charge on C4 be10.0 after the switch is opened?
