### Electrical Circuit Analysis with Light Bulbs #### 1. Circuit Description and Analysis A. The circuit provided consists of an ideal battery connected to 7 identical light bulbs as illustrated in the diagram: ![Circuit Diagram](https://example.com/circuit-diagram.png) <!-- placeholder for image URL --> **Diagram Description:** - The circuit is powered by a 9V battery. - The light bulbs are numbered from 1 to 7. - The setup includes both series and parallel connections. - Bulbs 1 and 2 are in series. - Bulbs 3 and 4 are connected in parallel with each other and collectively in series with the series combination of bulbs 1 and 2. - Bulbs 5, 6, and 7 are arranged in a configuration that can influence the current and brightness based on the circuit paths and connections. **Tasks:** 1. **Brightest to Dimmest Ranking:** i. Evaluate the brightness of bulbs 1, 3, 5 and 7. Rank them from the brightest to the dimmest. If any bulbs are equally bright or not lit, state so explicitly. **Explanation:** - You need to consider the current paths and potential drops across each bulb, examining series and parallel impacts on their brightness. 3. **Effects of Removing Bulb 5:** iii. If bulb 5 is removed, leaving its socket empty: - Will the current through the battery increase, decrease, or remain unchanged? Explain: - Analyze how the removal of bulb 5 impacts the total circuit resistance and, consequently, the current drawn from the battery. 4. **Impact on Bulb 1's Brightness:** iv. Determine the effect on bulb 1's brightness upon the removal of bulb 5: - Will the brightness increase, decrease, or remain the same? Explain: - Consider how the new circuit configuration affects the voltage drop across bulb 1. 5. **Impact on Bulb 4's Brightness:** v. Determine the effect on bulb 4's brightness upon the removal of bulb 5: - Will the brightness increase, decrease, or remain the same? Explain: - Evaluate the current distribution changes and potential impact on bulb 4 due to the removal of bulb 5. By following these steps and considerations, one can comprehensively analyze the electrical behavior of the circuit and
