**Title: Circuit Analysis for Educational Purposes**

**Introduction:**

Consider the resistive circuit shown, where \( R = 1 \, \text{k}\Omega \).

**Diagram Description:**

The circuit includes a voltage source \( V_s \) and several resistors. The resistors are arranged as follows:

- Two resistors in series with the voltage source.
- A middle branch consisting of another resistor \( V_1 \) connecting to the junction of the parallel resistors.
- Four resistors in total connected throughout the circuit.
- A resistor connected across providing the voltage \( V_o \).

**Exercises:**

a. **Resistance as Seen by the Voltage Source \( V_s \)**

   What is the total resistance seen by the voltage source if all resistors are of \( 1 \, \text{k}\Omega \)?

b. **Voltage \( V_1 \) in Terms of \( V_s \)**

   Determine the value of \( V_1 \) in the circuit concerning the source voltage \( V_s \).

c. **Voltage \( V_o \) in Terms of \( V_s \)**

   Determine the value of \( V_o \) in relation to the source voltage \( V_s \).

d. **4-Band Color Code for 1 kΩ Resistors**

   Identify the 4-band color code of the \( 1 \, \text{k}\Omega \) resistors given a tolerance of \( \pm 10\%\).

**Explanation of the Circuit Elements:**

The diagram illustrates a planar circuit with a structural symmetry axis in the middle. This configuration influences the voltage distribution across various resistors.

**Conclusion:**

The exercise aims to provide learners with practical understanding of series-parallel resistor circuits, voltage distribution, and resistor specification through color codes.
