**Circuit Analysis Problem**

**Description:**
Consider the circuit shown in the figure below. (Let \( R = 28.0 \, \Omega \).)

The circuit consists of the following components:

- Two 10.0 \(\Omega\) resistors in parallel.
- A 5.00 \(\Omega\) resistor in parallel with the 10.0 \(\Omega\) resistors.
- A power supply providing 25.0 V across the parallel combination of resistors.
- Another 5.00 \(\Omega\) resistor connected in series with the parallel section.
- A resistor \( R = 28.0 \, \Omega \) labeled near point \( b \).

**Tasks:**

(a) Find the current in the 28.0-\(\Omega\) resistor.
- Answer box: ______ A

(b) Find the potential difference between points \( a \) and \( b \).
- Answer box: ______ V

**Diagram Information:**

- The diagram shows nodes \( a \) and \( b \) at the ends of the parallel section.
- The potential source (battery) is connected across this parallel combination.
- A series connection is shown with a 5.00 \(\Omega\) resistor connected from point \( a \) leading into the parallel network, which then proceeds through the resistor \( R = 28.0 \, \Omega \) connected to point \( b \).

**Objective:**
Solve for the unknown electrical quantities using Ohm’s Law and parallel/series circuit analysis principles.
