Step-down transformer converts high voltage and low current into:

• A. Low voltage and high current
• B. High voltage and low current
• C. None of these
• D. How voltage and high current

Answer: (A)

In step up votlage,
Output votlage > Input votlage
Output current < Input current

In step down transformer
Output votlage < Input votlage
Output current > Input current.
Power and frequency remains almost constant in stepup or stepdown transformer.
