Question
1. For which configuration of the switches is lightbulb L3 the brightest? 2. Rank the lightbulbs in terms of their brightness (from high to low) when switches are closed.
In the figure below, all the light bulbs have the same resistance assumed to be constant. The switches are labeled S1 and S2. The emf of the battery is E.

**Diagram Explanation:**

- The circuit includes a battery with emf labeled as E.
- Two switches are present: S1 and S2.
- There are six light bulbs, labeled L1 through L6.
  
  - **L1 and L2:** These are in parallel with each other and are controlled by switch S1.
  - **L3:** This light bulb is in series with the parallel combination of L1 and L2.
  - **L4, L5, and L6:** These are in parallel with each other and are controlled by switch S2.
  
- The circuit is arranged such that the battery connects through the series and parallel combinations of bulbs and switches.
