Understanding the Turns Ratio Equation in Transformers

This video tutorial explains how the potential difference across the primary and secondary coils of a transformer depends on the number of turns of wire in each coil. It introduces the turns ratio equation and demonstrates its application through examples with different configurations of coil turns. The tutorial shows how to calculate the potential difference across the secondary coil when the number of turns on the primary and secondary coils varies.

What is the function of a transformer?

How does the potential difference across the secondary coil depend on the primary coil?

What equation relates the potential differences and the number of turns in a transformer?

If a transformer has 8 turns on both coils and the primary potential difference is 230 volts, what is the secondary potential difference?

What happens to the potential difference across the secondary coil if the number of turns on the primary coil is increased?

Calculate the potential difference across the secondary coil if the primary coil has 14 turns and the secondary coil has 7 turns with a primary potential difference of 110 volts.

What is the relationship between the number of turns on the primary and secondary coils and their respective potential differences?
