**4.53**

**a.** Find the branch currents \( i_a - i_e \) for the circuit shown in **Fig. P4.53**.

**b.** Check your answers by showing that the total power generated equals the total power dissipated.

---

**Figure P4.53 Description:**

The schematic diagram in Figure P4.53 represents an electrical circuit requiring analysis. Key components and connections are detailed below:

- **Current Sources:**
  - A 30 A current source is connected on the left side.

- **Resistors and Impedance:**
  - A 40 Ω resistor is connected in series with the 30 A current source.
  - A 10 Ω resistor is connected in the middle of the circuit.
  - A 35 Ω resistor is on the right, parallel to a controlled voltage source.

- **Controlled Sources:**
  - A dependent voltage source represented as \( 15i_d \) (pointing upwards) is located on the upper branch, between the 10 Ω and 35 Ω resistors.
  - A dependent current source represented as \( 3i_a \) connected in series with a 10 Ω resistor.

- **Voltage Source:**
  - A 150 V voltage source is connected on the far right.

- **Branch Currents:**
  - \( i_a \) is the current flowing through the 40 Ω resistor.
  - \( i_b \) is the current through the 10 Ω resistor.
  - \( i_c \) is the current through the 35 Ω resistor.
  - \( i_d \) is the controlling variable of the dependent sources.
  - \( i_e \) flows through the dependent voltage source \( 15i_d \).

The task involves determining individual branch currents within the network and verifying energy conservation by equating generated and dissipated power.
