For 2 capacitors in series, the equivalent capacitance is:
For capacitors in parallel, the equivalent capacitance is:
The charge stored by a capacitor:
From the figure, C1 and C2 are in parallel.
Therefore, C12 = C1 + C2 = 4 + 12 = 16 μF
C12 and C3 are in series.
What are the charge on and the potential difference across each capacitor in the figure ?
