can someone help me with the 2 problems below

 

### Transcription for Educational Website --- **Instructions:** Write a complete set of independent equations that could be used to solve this circuit. Do not attempt to solve the system of equations, or to simplify the circuit. If you have time, write the system of equations in matrix form, but this is not required. **Circuit Diagram Description:** The circuit diagram displays a network of resistors, independent voltage sources, independent current sources, and dependent sources connected in series and parallel configurations. - **Resistors** are labeled as follows: - \( R_1 = 1 \, \Omega \) - \( R_2 = 2 \, \Omega \) - \( R_3 = 4 \, \Omega \) - \( R_4 = 7 \, \Omega \) - \( R_5 = 8 \, \Omega \) - \( R_6 = 9 \, \Omega \) - \( R_7 = 12 \, \Omega \) - \( R_8 = 10 \, \Omega \) - **Voltage sources**: - A voltage source providing \( v_s = 3 \, V \) is located in series with \( R_3 \). - Another voltage source providing \( v_s = 15 \, V \) is located in series with \( R_7 \). - **Current sources**: - A current source providing \( i_s = 11 \, A \) is positioned parallel to \( R_7 \). - There is a source providing \( i_x = 5 \, A \) directed into a node below \( R_2 \). - **Dependent sources**: - A voltage source depending on \( i_x \), specified as \( v_x = 2i_x \), is in series with \( R_5 \). - A current source dependent on a yet unspecified variable, marked as \( i_d = 6 \beta i_x \), is located parallel to \( R_6 \). --- **Note:** The goal is to establish a system of independent equations involving Kirchhoff's laws, element laws (Ohm's Law), and relations for dependent sources. Use these to understand power distribution and relationships in the circuit. You may also express these equations in matrix form for simpler computational solutions, although this step is optional.

**Problem 1** Find the values of \( v \) and \( i \) in Figure 1, using the concepts of series/parallel resistor combinations, and also the voltage (or current) divider rule. **Figure 1 Explanation:** - The circuit contains a current source providing \( 8 \, \text{A} \). - There is a series of resistors connected in the circuit. - From the current source, the circuit first encounters a \( 5 \, \Omega \) resistor. - Next, the circuit has a \( 25 \, \Omega \) resistor in parallel with a complex network. - The parallel network includes: - A \( 20 \, \Omega \) and \( 10 \, \Omega \) resistor in series. - A resistor network with two \( 20 \, \Omega \) resistors in parallel, which are connected in series with another \( 20 \, \Omega \) resistor. - Finally, a \( 10 \, \Omega \) resistor in series with the current \( i \). - The task is to find the voltage \( v \) across the \( 25 \, \Omega \) resistor and the current \( i \) through the \( 10 \, \Omega \) resistor using series/parallel combinations and the voltage or current divider rule.
