Question
**Problem Statement:**

a) Calculate \( v_o \).

**Circuit Description:**

The circuit consists of the following elements and arrangements:

1. **Voltage Source:**
   - A 10 V DC voltage source is present on the left side of the circuit. The positive terminal is at the top.

2. **Resistors:**
   - A 30 Ω resistor is connected in series towards the top right of the circuit.
   - A 10 Ω resistor is in series with the 10 V source, placed horizontally.
   - Two branches are parallel after the 10 Ω resistor:
     - The first branch has a 40 Ω resistor.
     - The second branch runs horizontally with a 20 Ω resistor, leading to the dependent source.

3. **Dependent Source:**
   - A dependent voltage source on the right side expresses a value of \( 20i_1 \), dependent on the current \( i_1 \).

4. **Current and Voltage Notations:**
   - \( i_1 \) is the current flowing upwards through the 10 V source.
   - \( v_o \) is the voltage across the 40 Ω resistor, annotated with a + at the top and - at the bottom.

This setup requires you to apply circuit laws such as Ohm's Law, Kirchhoff's Voltage Law (KVL), or Kirchhoff's Current Law (KCL) to find the voltage \( v_o \). The dependent source introduces a variable element, requiring additional calculations to relate \( i_1 \) with \( v_o \).
