Statement I: When a current flows in the coil of a transformer, then its core becomes hot.
Statement II: The core of transformer is made of iron.

Text Solution
Verified by ExpertsD
Both Statement I and Statement II are correct.
When alternating current flows through the coil of a transformer, the core of transformer is magnetised and demagnetised repeatedly. The electrical energy taken by the core during magnetisation is not returned fully in demagnetisation. The energy remaining in the core appears in the form of heat.
