Question 1

What is the relationship between turns ratio and voltage transformation in a transformer?

Higher turns ratio steps down voltage
Lower turns ratio steps up voltage
Higher turns ratio steps up voltage

💡 Hint: Think about how turns ratio influences the voltage.

Question 2

Is the EMF induced in the secondary winding dependent on the frequency of the AC supply?

True
False

💡 Hint: Reflect on how changing frequencies might affect the operation.
