The Working Principle of a Transformer
The working principle of a transformer relies on electromagnetic induction, where an alternating current (AC) in the primary coil induces a voltage in the secondary coil. When an AC voltage is applied to the primary winding of a transformer, it creates a magnetic flux that surrounds it. This magnetic field then passes through the secondary winding, inducing a different voltage based on the turns ratio of the coils. In the case of a 240/120 transformer, the turns ratio is 2:1, facilitating the voltage step-down from 240V to 120V. Understanding this principle is vital for troubleshooting and maintenance.
- Based on electromagnetic induction
- Uses primary and secondary coils
- Turns ratio determines voltage conversion
- Induces voltage in the secondary coil
- Efficient energy transfer between coils
Applications of 240/120 Transformers
The 240/120 transformer finds utility in various environments, particularly residential buildings where different voltage levels are required for various devices.
