In the circuit diagram provided, the problem seems to involve calculating various electrical quantities, such as the currents (IA, IB, IC, ID), voltages (VC, VB, VA, VD), and potentially equivalent parameters like the Thevenin voltage (VTHV) and Thevenin resistance (RTHV).

Let's break down the steps required to solve this problem:

1. **Identifying Circuit Elements**:
   - Resistors (R1 = 2Ω, R2 = 3Ω, etc.)
   - Current sources (I1 = 1A, I2 = 2A, I3 = 3A)
   - Voltage sources (V1 = 3V, V2 = 2V)
   - Capacitor (C1 = 1μF)

2. **Currents**:
   - The diagram defines currents flowing in different loops: \(I_A\), \(I_B\), \(I_C\), and \(I_D\).
   - These can be solved using **Kirchhoff’s Current Law (KCL)** and **Kirchhoff’s Voltage Law (KVL)** in conjunction with Ohm’s Law.

3. **Voltages**:
   - The voltages across resistors can be determined using Ohm's Law \(V = IR\), once the currents are known.
   - The node voltages VA, VB, VC, VD are calculated using KVL by summing the voltage drops around loops.

4. **Thevenin Equivalent**:
   - To calculate the Thevenin voltage (VTHV) and Thevenin resistance (RTHV), we would isolate the portion of the circuit looking into terminals A and B. This involves:
     - Open-circuiting the current sources.
     - Calculating the open-circuit voltage (VTHV).
     - Calculating RTHV by replacing all sources with their internal resistances (short-circuit voltage sources, open-circuit current sources).

### Next Steps:
Would you like me to proceed with solving the specific currents and voltages using the laws and techniques mentioned?

Let me know if you'd like detailed steps for solving the circuit! Meanwhile, here are 5 questions for further understanding:

1. What is the direction of current flow in each loop?
2. How do you apply KVL to the leftmost loop in the circuit?
3. How can the Thevenin equivalent be simplified using superposition?
4. What happens if the capacitor is taken into account for frequency-domain analysis?
5. How do current sources I1, I2, and I3 interact with the rest of the circuit elements?

**Tip**: Always double-check the polarity of voltage sources and current directions before applying KVL or KCL to avoid sign errors!
