Question

Statement A: Step up transformer converts low voltage, high current to high voltage, low current.
Statement B: Transformer works on both ac and dc.

• A. A is true but B is false
• B. Both A and B are true
• C. A is false but B is true
• D. Both A and B are false

Answer 1

The correct option is A A is true but B is false

Step up transformer increases the voltage in secondary coil and decreases current in secondary coil. Transformer works only on ac current because in DC current, there is no change of flux associated with the coil
