The correct Answer is:
To solve the problem, we need to understand the behavior of electrical circuits, specifically when components are connected in series. ### Step-by-Step Solution: 1. **Identify the Power Ratings**: - The power rating of the first bulb (P1) is 100 W. - The power rating of the second bulb (P2) is 40 W. 2. **Understand the Series Connection**: - In a series circuit, the same current flows through all components. Therefore, if the current through the 100 W bulb is given as 1 A, the current through the 40 W bulb will also be 1 A. 3. **Calculate the Current through the 40 W Bulb**: - Since both bulbs are in series, the current (I) through the 40 W bulb is equal to the current through the 100 W bulb. - Thus, I = 1 A. 4. **Conclusion**: - The current through the 40 W bulb is also 1 A. ### Final Answer: The current through the 40 W bulb is 1 A. ---
