Question
The problem involves analyzing a circuit to find the currents \( I_A, I_B, I_C, I_D, \) and \( I_E \), and the power for each of the power sources. 

### Circuit Description:

- **Voltage Sources:**
  - A 10V source is present at the top of the circuit, with its positive terminal connected to a 4Ω resistor and its negative terminal connected to two 3Ω resistors and a 2A current source in parallel.
  - A 20V source is located at the bottom, with its negative terminal connected to a 2Ω resistor and positive terminal toward the center of the circuit.

- **Current Sources:**
  - A 2A current source on the left directs current into a 7Ω resistor.
  - A 3A current source in the middle directs current towards the right side of the circuit.

- **Resistors:**
  - The resistors in the circuit are as follows: 
    - In series/parallel on the left: Two 3Ω resistors and a 7Ω resistor.
    - In parallel: 4Ω, 2Ω, 5Ω, and 1Ω resistors.

- **Branch Currents:**
  - \( I_A \) flows upwards through a 3Ω resistor.
  - \( I_B \) flows downwards through a 1Ω resistor next to the 10V source.
  - \( I_C \) flows downwards from the positive terminal of the 20V source through a 2Ω resistor.
  - \( I_D \) flows upwards through the 2Ω resistor.
  - \( I_E \) flows downwards through the 5Ω resistor.

### Task:

- **Currents:** Calculate the branch currents: \( I_A, I_B, I_C, I_D, \) and \( I_E \) using Kirchhoff’s laws and Ohm's law.
- **Power:** Calculate the power for each source using the formula \( P = IV \), where \( P \) is power, \( I \) is current, and \( V \) is voltage.

The solution involves applying circuit analysis techniques such as mesh analysis or nodal analysis to determine the required values.
