**Transcription and Explanation for Educational Purposes**

**Text:**

"For the circuit below, use nodal analysis to find the voltages \(V_A\), \(V_B\), \(V_C\), \(V_D\), and \(V_E\). (Provide your calculations and reasoning for your answer.)"

**Circuit Diagram Explanation:**

The circuit diagram consists of several components connected in a series-parallel configuration, including resistors and voltage sources. Here's a detailed breakdown:

1. **Voltage Sources:**
   - **V2**: A 40V DC voltage source is connected on the left side of the circuit.
   - **V1**: A 20V DC voltage source is connected on the right side, after several resistors.

2. **Resistors:**
   - **R1** (5kΩ): Connected in series after V2 and before the first node (V_D).
   - **R2** (1kΩ): Connected between node V_D and node V_C.
   - **R3** (2kΩ): Connected between node V_C and node V_B.
   - **R4** (5kΩ): Connected in parallel between node V_D and ground.
   - **R5** (2kΩ): Connected in parallel between node V_C and ground.
   - **R6** (1kΩ): Connected in series between node V_B and node V_A, just before V1.
   - **R7** (500Ω): Connected between node V_A and ground.

3. **Nodes:**
   - **\(V_A\)**: Voltage at the node after R6 and V1.
   - **\(V_B\)**: Voltage at the node between R3 and R6.
   - **\(V_C\)**: Voltage at the node between R2 and R3.
   - **\(V_D\)**: Voltage at the node between R1 and R2, and above R4.
   - **\(V_E\)**: Voltage at the node on the left side of V2.

**Nodal Analysis:**

To find the voltages \(V_A\), \(V_B\), \(V_C\), \(V_D\), and \(V_E\), apply nodal analysis by setting up KCL (Kirchhoff’s Current Law) equations at each node where the unknown voltages are present. Utilize Ohm’s
