The correct Answer is:
To analyze the given assertion and reason, let's break it down step by step: ### Step 1: Understanding the Assertion **Assertion (A)**: A transformer does not work on DC. - A transformer operates on the principle of electromagnetic induction, which requires a changing magnetic field to induce voltage in a secondary coil. ### Step 2: Understanding the Reason **Reason (R)**: DC neither changes direction nor magnitude. - Direct Current (DC) is characterized by a constant flow of electric charge in one direction. This means that both the direction and magnitude of the current remain constant over time. ### Step 3: Analyzing the Relationship - Since a transformer relies on a changing magnetic field to function, it requires an alternating current (AC) that varies in both direction and magnitude. - With DC, there is no change in direction or magnitude, which means there is no changing magnetic field to induce voltage in the secondary coil of the transformer. ### Step 4: Conclusion - Both the assertion and the reason are correct. The reason correctly explains why the assertion is true. Therefore, the answer is that both A and R are correct, and R is the correct explanation of A. ### Final Answer Both the assertion (A) and the reason (R) are correct, and R is the correct explanation of A. ---
