Transformers

In an ideal transformer, the turns ratio is given by the equation: , where:

• is the number of turns in the primary coil.
• is the number of turns in the secondary coil.
• is the voltage across the primary coil.
• is the voltage across the secondary coil.

In this scenario, the turns ratio is . Plugging this into the transformer equation, we have:

This implies that:

Thus, the voltage ratio is:

The correct answer is 2:1
