Question

Why does step-up transformer have more turns in the secondary than in the primary?

Answer 1

Answer:

because to increase the voltage and to decrease current

Answer 2

Dear Student,

● Step-up transformer have more turns in the secondary than in the primary coil because -

• Voltage transformation ratio depends on ratio of secondary coils to primary coils.

Voltage transformer ratio = N(secondary) / N(primary)

• Hence to increase voltage in step up transformer, secondary coil have more turns than primary coil.
• Current is reduced proportionately in step up transformer.

Thanks dear. Hope this helps you...
