Question
Solve for VL and IL using superposition.
The image depicts an electrical circuit diagram titled "Figure 4." The circuit consists of the following components:

1. **Voltage Sources:**
   - \( V_{s1} \) is a 5 V DC source.
   - \( V_{s2} \) is a 12 V DC source.

2. **Resistors:**
   - \( R1 \) is a 10 kΩ resistor.
   - \( R2 \) is a 10 kΩ resistor.
   - \( R3 \) is a 1 kΩ resistor.
   - \( R4 \) is a 6.2 kΩ resistor.
   - \( R_L \) is a 1 kΩ load resistor.

3. **Connections and Current Flow:**
   - The circuit is grounded at one point, as indicated at the bottom of \( V_{s2} \).
   - Components \( R1 \) and \( R2 \) are connected in series between the positive terminal of \( V_{s1} \) and the junction of \( V_{s2} \) and \( R4 \).
   - \( R3 \) and \( R4 \) form another series path between the positive terminal of \( V_{s2} \) and the junction of \( R1 \) and \( R_L \).
   - The current \( I_L \) passes through the load resistor \( R_L \), and the voltage across \( R_L \) is labeled as \( V_L \).

This type of circuit can be used for analysis of series-parallel connections and determination of current and voltage in each branch according to Ohm's and Kirchhoff's laws.
