Transcribed Image Text:The image depicts an electrical circuit featuring resistors and a voltage source. The configuration and values of the resistors are as follows:
1. **Resistor R1**: This resistor is labeled as 9.0 ohms (Ω). It is positioned in series with the voltage source (depicted as ε).
2. **Resistor R2**: This resistor has a value of 4.0 ohms (Ω) and is placed in series with the voltage source and R1.
3. **Resistor R3**: This resistor is valued at 6.0 ohms (Ω) and is connected in parallel with R4.
4. **Resistor R4**: This resistor shows a value of 3.0 ohms (Ω) and forms a parallel connection with R3.
The circuit starts with the voltage source, followed by R1. After R1, the circuit splits, with one path containing R2 and the other branching off to the parallel combination of R3 and R4. The parallel arrangement of R3 and R4 provides an alternative path for the current between the series components R1 and R2.
This type of circuit configuration is useful for understanding concepts such as series and parallel resistances, voltage division, current paths, and how these elements interact within an electrical circuit.
