Question

Two resistors and two uncharged capacitors are arranged as shown in . Then a potential difference of 24 V is applied across the combination as shown.

A. What is the potential at point a with switch S open? (Let V=0 at the negative terminal of the source.)

B. What is the potential at point b with the switch open?

C. When the switch is closed, what is the final potential of point b?

D. How much charge flows through the switch S after it is closed?

I am really bad at these so a solid explanation and a numerical answer will be appreciated!

a) 24 * 4.4/ (4.4 + 8.8) = 8V

b) 24 * 0.48/ (0.36 + 0.48) = 13.71V

c) 8V beacuse all the current floes thrught he resistors, so V= I(R1 + R2) ,so Vb = Va =VR1/(R1+R2)

d) Q = Q1 + Q2 = C1V1 + C2V2

= 0.48*16 + 0.36*8 = 10.56 uC
