What is the primary purpose of a transformer?

The primary purpose of a transformer is to increase or decrease voltage. Transformers are electrical devices that work on the principle of electromagnetic induction to transfer electrical energy between two or more circuits. They do this by converting high voltage, low current electricity to low voltage, high current electricity, or vice versa, depending on their design.

Transformers are essential in electrical power systems because they allow voltage levels to be adjusted for efficient transmission over long distances and then transformed back to usable levels for consumers. For example, power plants generate electricity at a higher voltage for transmission to reduce energy losses and then use transformers to lower the voltage for safe distribution to homes and businesses.

Understanding the role of transformers is vital, as they help maintain the stability and efficiency of electrical power systems, making them invaluable components in modern electrical infrastructure.
