To calculate the equivalent capacitance \( C_{\text{eq}} \) of the circuit shown in the image, we need to analyze the configuration of the capacitors.

### Analysis of the Circuit

1. **Identify Series and Parallel Connections**:
   - \( C2 \) and \( C3 \) are in series.
   - The series combination of \( C2 \) and \( C3 \) is in parallel with \( C4 \).
   - Finally, \( C1 \) is in series with the combination of \( C2 \), \( C3 \), and \( C4 \).

2. **Calculate the Equivalent Capacitance of \( C2 \) and \( C3 \) in Series**:
   The formula for capacitors in series is given by:
   \[
   \frac{1}{C_{23}} = \frac{1}{C2} + \frac{1}{C3}
   \]
   Therefore,
   \[
   C_{23} = \frac{C2 \cdot C3}{C2 + C3}
   \]

3. **Calculate the Equivalent Capacitance of \( C_{23} \) and \( C4 \) in Parallel**:
   The formula for capacitors in parallel is given by:
   \[
   C_{234} = C_{23} + C4
   \]

4. **Calculate the Equivalent Capacitance of \( C1 \) and \( C_{234} \) in Series**:
   Using the series formula again:
   \[
   \frac{1}{C_{\text{eq}}} = \frac{1}{C1} + \frac{1}{C_{234}}
   \]
   Therefore,
   \[
   C_{\text{eq}} = \frac{C1 \cdot C_{234}}{C1 + C_{234}}
   \]

### Final Formula

Substituting \( C_{234} \) back into the final series combination:
\[
C_{\text{eq}} = \frac{C1 \cdot \left( \frac{C2 \cdot C3}{C2 + C3} + C4 \right)}{C1 + \left( \frac{C2 \cdot C3}{C2 + C3} + C4 \right)}
\]

This gives the equivalent capacitance of the entire circuit.

### Example Calculation

If we assume specific values for \( C1, C2, C3, \) and \( C4 \), we can plug those values into the formula to get a numerical result.

Do you want to provide specific values for \( C1, C2, C3, \) and \( C4 \), or should we assume some example values to perform a calculation?

Would you like any further details or have any questions on this calculation? 

Here are 5 related questions to expand the topic:

1. How does the equivalent capacitance change if all capacitors have the same value?
2. What is the effect of increasing \( C4 \) on the equivalent capacitance?
3. How can the equivalent capacitance be measured experimentally?
4. What happens to the equivalent capacitance if \( C1 \) is removed from the circuit?
5. How does the arrangement of capacitors affect the charging and discharging behavior of the circuit?

**Tip:** When dealing with capacitors in complex circuits, break the circuit into smaller sections and solve step-by-step, combining series and parallel combinations iteratively.
