3.(a) Find the equivalent capacitance of figure below. (b) If C, breaks down electrically, becoming equivalent to a conducting path, calculate the changes in the charge and in the potential difference across capacitor C ? Assume: C1= 10.3/LF, C2 =4.8/LF, C; =3.9/F, AV =115V. (5-points) C1 C2 AV =115V C3
