The correct Answer is:
To solve the question, we need to analyze the assertion and the reason provided: ### Step 1: Understand the Assertion The assertion states that "Kirchhoff's junction rule can be applied to a junction of several lines or a point in a line." **Explanation**: Kirchhoff's junction rule, also known as the first law of Kirchhoff, states that the total current entering a junction must equal the total current leaving the junction. This is based on the principle of conservation of charge. ### Step 2: Understand the Reason The reason states that "When steady current is flowing, there is no accumulation of charges at any junction in series with a galvanometer." **Explanation**: In a steady current situation, charges are not building up at any junction. This means that the current entering the junction is equal to the current leaving the junction, which is a fundamental requirement for applying Kirchhoff's junction rule. ### Step 3: Evaluate the Assertion and Reason Both the assertion and the reason are correct. The assertion is valid because Kirchhoff's junction rule can indeed be applied to any junction where currents are converging or diverging. The reason correctly explains why this is the case, as steady current implies no charge accumulation. ### Conclusion Since both the assertion and the reason are correct, and the reason provides a correct explanation for the assertion, the answer to the question is that both the assertion and reason are true, and the reason is the correct explanation for the assertion. ### Final Answer Both the assertion and reason are correct, and the reason is the correct explanation for the assertion. ---
