Question

Three capacitors with capacitances C1 = 7.9 μF, C2 = 2.1 μF, and C3 = 5.3 μF are connected in a circuit as shown in the figure, with an applied potential of V. After the charges on the capacitors have reached their equilibrium values, the charge Q2 on the second capacitor is found to be 70. μC. 

a) What is the charge, Q1, on capacitor C1

b) What is the charge, Q3, on capacitor C3?

c) How much voltage, V, was applied across the capacitors?

The image depicts an electrical circuit diagram involving capacitors. Here's a detailed description:

- The circuit contains three capacitors labeled \( C_1 \), \( C_2 \), and \( C_3 \).
- \( C_1 \) and \( C_2 \) are connected in parallel. This means both capacitors share the same two nodes in the circuit and thus have the same voltage applied across them.
- The combination of \( C_1 \) and \( C_2 \) is connected in series with \( C_3 \). This means that the net charge on \( C_3 \) is the same as the total charge on the combination of \( C_1 \) and \( C_2 \).
- \( V \) represents the voltage source connected across the entire arrangement of capacitors. This setup suggests that the voltage source is in series with the parallel combination of \( C_1 \) and \( C_2 \), and the series \( C_3 \).
- This configuration is often used to discuss the concepts of equivalent capacitance in series and parallel connections within electrical circuits.
