Answer 1

Explanation:

The toroidal core transformer, utilizes a ring or doughnut-shaped core material.
This design enhances its performance by minimizing leakage inductance and achieving high inductance and Q factors.
The continuous circular magnetic path in a toroidal core reduces magnetic flux leakage, resulting in efficient energy transfer and reduced electromagnetic interference.
The toroidal shape also allows for a compact and space-efficient design.
These transformers find applications in audio equipment, power supplies, and other electronics where low leakage and high efficiency are crucial. Overall, the toroidal core transformer stands out for its superior magnetic properties and practical design advantages.
