The capacitor is connected into the circuit as shown in the figure below, with an open switch, a resistor, and an initially uncharged capacitor of capacitance 3C. The switch is then closed, and the circuit comes to equilibrium 3C In terms of Q and C, find the following (a) the final potential difference between the plates of each capacitor smaller capacitor f larger capacitor f= (b) the charge on each capacitor ?smaller capacitor = larger capacitor- (c) the final energy stored in each capacitor smaller capacitor Uf larger capacitor Uf- (d) the internal energy appearing in the resistor 2. -14 points My Notes GP4.pdf Show all downloads.... x 9:29 PM 2/9/2016 Search the web and WindowsExplanation / Answer
Since charge is conserved, Charge Q will be on an effective capacitance of 4C.
We have general formula, V= Q/C
V =Q/4C
b)
Q=CV
On the C capacitor (small) Q= C . (Q/4C) = Q/4
On the 3C capacitor (large) Q = 3C . (Q/4C) = 3Q/4
c)
we have
E= (1/2) CV2
On the C capacitor ( small): E= Q2/32C
On the 3C capacitor (large) : E = (3Q2)/ 32C
