Find the current i and the voltage V_{A from given circuit}

**Circuit Diagram Description**

This is a schematic diagram of an electrical circuit. Here are the components and their configuration:

1. **Current Source**: The circuit includes a current source providing a current of 5A.

2. **Resistor R1 (12Ω)**: Connected in series to the current source is a 12-ohm resistor. This is connected to point A in the circuit.

3. **Node A**: A common connection point (node) is labeled as "A" where multiple paths diverge.

4. **Series Resistors (2Ω and 5Ω)**: After node A, there is a vertical path consisting of a 2-ohm resistor, through which current "i" is marked, leading in the direction indicated by an arrow.

5. **Parallel Resistor (20Ω)**: This resistor is placed in parallel with the 5-ohm resistor, creating a branch parallel to the 2-ohm resistor.

6. **Ground Connection**: The connection point beneath the 12-ohm resistor is marked as ground.

**Diagram Analysis**

- The circuit begins with a 5A current source.
- Current flows through the series-connected 12-ohm resistor reaching point A.
- From point A, the circuit splits into two paths:
- One path through the 2-ohm resistor.
- Another parallel path through the 20-ohm resistor leading to a 5-ohm resistor.
- These paths reconverge to complete the circuit.

This schematic is designed to understand the flow of current and distribution across resistors in a parallel and series configuration, which is crucial in analyzing electrical networks.

Expert Solution

Step 1

From the circuit, the 5Ω resistor is connected in parallel with 20Ω resistor and the parallel combination of 5Ω resistor and 20Ω resistor is in series with 2Ω resistor. The complete combination 5Ω resistor, 20Ω resistor and 2Ω resistor is parallel with 12Ω resistor. The current supplied to the parallel combination 12Ω resistor and combination 5Ω resistor, 20Ω resistor and 2Ω resistor is the current from the current source.

Thus, the complete resistance (R₁) of the combination of 5Ω resistor, 20Ω resistor and 2Ω resistor is given by:

To calculate the current flowing in complete resistance (I₁), apply current division rule between 12Ω resistor and R₁:
