Explanation
(a) The statement means that an electric charge of 5\(\mu\)F is stored by the fully charged capacitor when connected to a d.c source of 1V.
(b)(i)




(i) Factors


(ii) Form of dependence




- Common area of plates
- Distance between plates
- Permitivity or nature of dielectric


- Direct proportionality
- Inverse proportionality
- Direct proportionality





(c)(i)


(ii) \(\frac{1}{C} = \frac{1}{C_1} + \frac{1}{C_1} + \frac{1}{C_3}\)
= \(\frac{1}{8} + \frac{1}{12} + \frac{1}{20} = \frac{3 + 2 + 1}{24}\)
C = \(\frac{24}{6} = 4 \mu F\)
(iii) Q = CV = 4 x 10\(^{-6}\) x 90 = 360\(\mu\)C
charge on 8\(\mu\) FV = \(\frac{Q}{C} = \frac{360}{8}\) = 45V
