Transcribed Image Text:The image presents an electrical circuit diagram with the task to "Solve for the resistance R."
### Circuit Details:
1. **Voltage Sources:**
- 20V source at the bottom left.
- An additional voltage source labeled 2V is present near the top right.
2. **Resistors and Currents:**
- A resistor labeled `R` is on the top left side of the circuit.
- A 2-ohm resistor is connected in series with the 20V source.
- A 9-ohm resistor is connected in parallel after the 2-ohm resistor.
- An 8-ohm resistor is connected in series with the 2V voltage source on the right side.
- Current of 3A is flowing to the left near the bottom.
- Current of 4A is flowing to the right near the top.
The diagram is drawn using different colors for clarity:
- Red indicates resistors.
- Green indicates current flow.
### Objective:
The objective of the diagram is to determine the value of the unknown resistor `R` in the circuit using the given information about currents, voltages, and other resistances.
