The correct Answer is:
To solve the assertion-reason question, we need to analyze both the assertion (A) and the reason (R) provided. ### Step 1: Analyze the Assertion (A) The assertion states: "Direct current is more dangerous than alternating current of the same value." - **Scientific Understanding**: It is generally accepted that alternating current (AC) is more dangerous than direct current (DC) of the same value. This is due to the physiological effects of AC on the human body, particularly its impact on the heart. AC can cause more severe muscle contractions and can disrupt the heart's rhythm more easily than DC. ### Step 2: Analyze the Reason (R) The reason states: "An electrocuted person sticks to the direct current line while alternating current repels the person from the line." - **Scientific Understanding**: The first part of the reason is true; a person in contact with a DC source may find it difficult to let go because the current is constant. However, the second part of the reason is misleading. While it is true that AC current alternates and has moments where it can be zero, it does not "repel" a person. Instead, it is the alternating nature that gives a brief opportunity to escape, but if the current is strong enough, it can still be fatal. ### Step 3: Conclusion - **Assertion (A)**: False (AC is more dangerous than DC). - **Reason (R)**: Partially true (the first part is true, but the second part is misleading). Thus, both the assertion and the reason are incorrect in the context of the question. The correct answer is that both the assertion and the reason are false. ### Final Answer Both assertion and reason are false. ---
