The equivalent capacitance between b and c is 9.2 PF.
A capacitor is a device which store electrical energy in an electric field.
A. capacitor c2 and c3 are in parallel
Cbc = C2 + C3
Cbc = 9.8 + 8.0
Cbc = 18 PF
B. When C1 and Cbc are in series
[tex]\rm Cac = \dfrac{C_1 \times C_b_c}{C_1 + C_b_c} = \dfrac{19 \times 18}{19 + 18 } = 9.24\;PF[/tex]
Thus, the equivalent capacitance between b and c is 9.2 PF.
