To calculate the equivalent capacitance \( C_g \) for the given circuit, let's analyze the structure.

### Circuit Description:
- \( C_1 \) is in series with the parallel combination of \( C_2 \), \( C_3 \), and \( C_4 \).
  
#### Step-by-step process:
1. **Capacitors \( C_2 \), \( C_3 \), and \( C_4 \) are in parallel**:
   The total capacitance for capacitors in parallel is the sum of their capacitances:
   \[
   C_{p} = C_2 + C_3 + C_4
   \]
   Substituting the values:
   \[
   C_{p} = 458\textrm{ nF} + 215\textrm{ nF} + 29\textrm{ nF} = 702\textrm{ nF}
   \]

2. **Capacitors \( C_1 \) and \( C_p \) are in series**:
   The formula for capacitors in series is:
   \[
   \frac{1}{C_g} = \frac{1}{C_1} + \frac{1}{C_p}
   \]
   Substituting the values:
   \[
   \frac{1}{C_g} = \frac{1}{43\textrm{ nF}} + \frac{1}{702\textrm{ nF}}
   \]
   Solving this will give us the total equivalent capacitance \( C_g \).

Let me compute that.The equivalent capacitance \( C_g \) of the given circuit is approximately \( 40.52 \, \text{nF} \).

Would you like further clarification on any step or more details about the calculations?

Here are five related questions for further exploration:
1. How would the equivalent capacitance change if \( C_4 \) were removed from the circuit?
2. What is the effect of adding more capacitors in parallel with \( C_2 \)?
3. How would the total capacitance change if \( C_1 \) was increased to \( 100 \, \text{nF} \)?
4. Can this circuit's behavior be compared to that of an inductor circuit?
5. What would happen to the equivalent capacitance if all capacitors were connected in series?

**Tip**: In capacitive circuits, capacitors in parallel add directly, while those in series combine inversely like resistors.
