**Finding the Equivalent Resistance between Terminals a and b** In this electrical network diagram (Figure 4), we aim to find the equivalent resistance between two terminals, labeled as 'a' and 'b'. The network consists of multiple resistors arranged in a combination of series and parallel connections. **Components and Connections:** - The circuit is made up of the following resistors: - A 16-ohm resistor connected in series with an 8-ohm resistor. - A parallel connection with a branch containing a 2-ohm resistor positioned between terminal 'a' and a junction. - From this junction, a path leads directly to a 30-ohm resistor connected to terminal 'b'. - Another path from the same junction includes an 8-ohm resistor. - The upper path from terminal 'a' combines the series of a 2-ohm resistor and leads directly to the junction connecting to the 30-ohm and 80-ohm resistors. - On the right side of the diagram, near terminal 'b', there are series-connected resistors of 60-ohms and 28-ohms leading to a junction: - From this junction, one branch consists of a 15-ohm resistor which reconnects to the network. - Another branch returns to the 30-ohm resistor, which is also part of the main parallel network. The task is to calculate the total resistance between terminals 'a' and 'b' considering these series and parallel configurations.

**For the circuit shown in Figure 3:** 1) Solve for \( i_x \) and \( i_s \). 2) What types of sources are present in this circuit? --- **Figure 3: Circuit Diagram** - The circuit includes: - A current source labeled \( i_s \) on the left. - A 5-ohm resistor connected in series with the current source. - A dependent current source labeled \( \frac{i_x}{2} \), connected in parallel with the 5-ohm resistor. - A 10-ohm resistor through which current \( i_x \) flows to the right. - A 15-ohm resistor connected to a 30V voltage source, aligned in a loop with the 10-ohm resistor. **Types of sources:** - **Independent Current Source**: \( i_s \) - **Dependent Current Source**: \( \frac{i_x}{2} \) (dependent on the current \( i_x \)) - **Independent Voltage Source**: 30V The problem requires analyzing the circuit to find the values of \( i_x \) and \( i_s \) as well as identifying all the types of sources present.
