Red ed Yello Red Blue B Yellow Yellow Blue Red e Volts B. In a recent Science Olympiad, six capacitors(one blue, two red, and three yellow) are attached to a circuit with a six volt battery as shown below. Assuming that all capacitors of the same color have the same capacitance, and that they have been waiting forever for someone to come along and work with them, answer the following questions: -5. A student measures the voltage drop of 4 Volts between points D and E. What can she conclude about charge on the blue and red capacitors on the wire running from D to F? (5 points) * c) Qred= Qblue

Explanation / Answer

VBlue = 4 V

VRed = 2 V

CBlue & CRed from Dto F are in series

charge is same on both

QBlue = QRed

option (a)

______________________

6)

from capacitance expression

C = Q/V

CBlue = Q/VBlue

CRed = Q/VRed

CBlue/CRed = VRed/VBlue

CBlue/CRed = 2/4 = 1/2

Cred = 2*Cblue

option (b)

_______________

7)

Vyellow = 3 V

VBlue = 3 V

Qblue = Q

Qyellow = Q/3

Cblue = Qblue/Vblue

Cyellow = Qyellow/Vyellow

Cblue/Cyellow = (Qblue/Vblue)*(Vyellow/Qyellow)

Cblue/Cyellow = (Q/3)*(3/(Q/3)) = 3

Cblue = 3*Cyellow

Cred > Cblue > Cyellow

option (a)

_______________________

8)

all yellow are in parallel

equivalent = 3*Cyellow

option (a)
