Question
E=8.3V and R=5 ohms a) Find the current in the 2 ohm resistor (in mA) b) Find the potential difference between points a and b (in V)
This image depicts an electrical circuit diagram with the following components:

1. **Voltage Source**:
   - A 12.0 V battery on the top left, with its positive terminal connected to the circuit.

2. **Resistors**:
   - Three resistors are connected in the circuit:
     - A 4.00 Ω resistor on the top horizontal path between points `a` and `b`.
     - A 2.00 Ω resistor in the middle horizontal path parallel to the first resistor.
     - Another resistor labeled `R` in the bottom horizontal path parallel to the other resistors.

3. **Connections**:
   - The circuit forms a parallel configuration with the three resistors as each path connects between nodes `a` and `b`.

4. **Additional Voltage Source**:
   - There is another voltage source labeled `ε` at the bottom, oriented with the positive terminal towards the right.

This diagram can be used to analyze current distribution, voltage drops across each resistor, and equivalent resistance in a parallel circuit setup. Understanding such diagrams is essential for solving circuit analysis problems in physics and electrical engineering.
