Using the circuit diagram above. Calculate the total charge in the circuit
-
A.
80(mu C) -
B.
35(mu C) -
C.
20(mu C) -
D.
16(mu C)
Correct Answer: Option D
Explanation
C – (C_1 + C_2 = 2 + 6 = mu F)
(frac{1}{C} = frac{1}{C_1} + frac{1}{C_1} + frac{1}{C_2} = frac{1}{8} + frac{1}{2})
C = (frac{8}{5 mu F})
Q = CV
= (frac{8}{5} times 10 = 16mu C)
