Iron losses are negligible during short-circuit test of transformer since

Iron losses are negligible during short-circuit test of transformer since

1. The current on secondary side is negligible
2. Full-load current is not supplied to the transformer
3. The voltage on secondary side does not vary
4. The voltage applied on primary side is low

Correct answer: 4. The voltage applied on primary side is low
