The capacitance of an infinite circuit formed by the repetition of the same link consisting of two identical capacitors, each with capacitance $C$ (figure), is

For section $AB$ of a circuit shown in figure, $C_1=1 \mathrm{\mu F},C_2=2 \mathrm{\mu F},E=10 \mathrm{V}$, and the potential difference $V_A-V_B=-10 V$. Charge on capacitor $C_1$ is:

Three capacitors $A,B$, and $C$ are connected in a circuit as shown in figure. What is the charge in $\mathrm{\mu C}$ on the capacitor $B$?

Three capacitors are connected as shown in the figure. Then, the charge on capacitor $C_1$ is
