Three capacitors each of capacitance 9 pF are connected in series.
(a) Capacitance of each of the three capacitors, C = 9 pF Equivalent capacitance (Ceq) of the combination of the capacitors is given by the relation, 1/Ceq=1/C+1/C+1/C=3/C=3/9=1/3 ⇒1/Ceq=1/3⇒Ceq=3 pF Therefore, total capacitance of...
