**Educational Website Content: Understanding Electrical Circuits**

**Description of Circuits:**

The image presents three different electrical circuits, labeled A, B, and C. Each circuit features a voltage source and multiple resistors.

**Circuit A:**
- Contains a 30 V voltage source.
- Includes two resistors in a series-parallel configuration: \( R_1 \) is in series with a parallel combination of \( R_2 \) and \( R_3 \).

**Circuit B:**
- Contains a 30 V voltage source.
- Consists of three resistors: \( R_1 \) in series with a parallel configuration of \( R_2 \) and \( R_4 \).

**Circuit C:**
- Contains a 30 V voltage source.
- Composed of three resistors: \( R_1 \), \( R_2 \), and \( R_3 \), all in series.

**Assumptions:**
For all circuits, unless otherwise specified, each resistor (\( R_1, R_2, R_3, R_4 \)) has a resistance of \( R = 10 \, \Omega \).

**Understanding the Layout:**

- **Series Configuration:** When resistors are in series, the total resistance is the sum of the individual resistances.
- **Parallel Configuration:** When resistors are in parallel, the total resistance can be calculated using the formula:
  \[
  \frac{1}{R_{\text{total}}} = \frac{1}{R_1} + \frac{1}{R_2} + \ldots
  \]

Each circuit configuration impacts the total resistance and current flow, demonstrating key principles of circuit design and analysis.
