**Understanding Light Bulb Connections:**Consider the following connection diagrams of light bulbs:**Diagram A:**- Features three light bulbs connected in series (one after another).**Diagram B:**- Shows three light bulbs connected in parallel (all bulbs connected independently across the same two points).**Diagram C:**- Depicts a mixed connection where two light bulbs are connected in parallel, and the third light bulb is in series with this parallel combination.**Diagram D:**- Represents two parallel light bulbs collectively in series with another single bulb.**Question:**How should the three identical light bulbs be connected to give the maximum brightness - A, B, C, or D? (NB: The brightness of a light bulb is dependent on the power \( P \) and is proportional to the current strength squared (\( P \propto I^2 \)) if the resistance \( R \) is the same.)**Hint:**Determine which combination will provide the smallest equivalent resistance and thus the strongest current.**Detailed Diagram Analysis:**- **Diagram A (Series Connection):** In a series connection, the equivalent resistance is the sum of all three resistances (\( R_{eq} = R_1 + R_2 + R_3 \)), leading to a high total resistance.- **Diagram B (Parallel Connection):** In a parallel connection, the reciprocal of the equivalent resistance is the sum of the reciprocals of each individual resistance (\( 1/R_{eq} = 1/R_1 + 1/R_2 + 1/R_3 \)). This results in a much lower equivalent resistance compared to series.- **Diagram C (Mixed Connection):** Here, the equivalent resistance is more complex. The two parallel resistances contribute collectively, and this parallel combination is in series with the third bulb.- **Diagram D (Series-Parallel Combination):** Equivalent resistance is calculated by taking the parallel of two bulbs in series with the third bulb, which results in moderate resistance.**Conclusion:**For maximum brightness, the configuration with the smallest equivalent resistance is preferred. Analyze the equivalent resistances to conclude that **Diagram B (Parallel Connection)** will provide the highest brightness.
