Question
**Exercise 22: Analysis of Resistive Network (Fig. 7.85)**

For the network shown in Figure 7.85, perform the following tasks:

a. **Determine RT** by combining the resistive elements in the given circuit.

b. **Find V1 and V4**, the voltages across the specified points in the circuit.

c. **Calculate I3**, ensuring the correct direction is noted.

d. **Determine Is** by analyzing the current through each element using Kirchhoff’s current law. Subsequently, calculate the total resistance (RT) using the formula \(RT = \frac{E}{Is}\).

---

### Diagram Explanation

- **Resistors:** 
  - \( R_1 = 16 \, \Omega \)
  - \( R_2 = 8 \, \Omega \)
  - \( R_3 = 32 \, \Omega \)
  - \( R_4 = 16 \, \Omega \)
  
- **Current:** 
  - The current \( I_3 \) flows through \( R_3 \).

- **Voltage Source:**
  - The battery provides a voltage \( E = 32 \, V\).

- **Other Points:**
  - Voltage points \( V_1 \) and \( V_4 \) are indicated across specific resistors or nodes within the circuit.

### Circuit Configuration

The circuit consists of four resistors arranged partially in series and parallel combinations, with a voltage source of 32 volts connected to them. The analysis involves applying fundamental principles such as series-parallel resistance combinations and Kirchhoff’s laws to solve for the desired electrical parameters.
