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.
