\nA transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction. Step-up transformers are specifically designed to increase (step up) the voltage from the primary coil to the secondary coil. They have more turns in the secondary coil than in the primary coil. Conversely, a step-down transformer decreases the voltage. Transformers are highly efficient, but they do not increase or decrease the total electrical power (ideally, power input equals power output, although small losses occur in real transformers).

\n– Step-up transformers increase voltage.
\n– They work based on electromagnetic induction.
\n– They are used in AC circuits.

\nStep-up transformers are commonly used in power transmission systems. Electricity is generated at a relatively low voltage at power plants. Step-up transformers increase the voltage to very high levels for transmission over long distances (reducing current and thus minimizing power loss due to resistance, P = I\u00b2R). At the receiving end, step-down transformers are used to reduce the voltage to safer levels for distribution and use in homes and industries.
