AIIMS 2019 Physics Transformers MCQ Question

Option A is correct because it represents the calculated output power (P_out) of the transformer, which is derived from the ideal transformer equation where input power equals output power (P_in = P_out). The calculation shows that with the given secondary voltage (V₂ = 12/5 V) and load resistance (R₂ = 10 Ω), the output power is 5.76 W, confirming the relationship between voltage, resistance, and power in an ideal transformer. Other options are not applicable as they do not provide relevant values or calculations related to the problem. Understanding the principles of transformers, including the conservation of energy and the relationship between voltage, current, and resistance, is crucial for solving such problems.
