how could I describe the physics of transformer?
A Step up transformer is outdoors a skill station and will enhance the voltage for the skill lines so it may bypass swifter and better parts. A step down transformer is after the skill lines to shrink the voltage and making it secure for domicile use.
A device by which you can increase or decrease the available AC mains voltage.
In electricity, a transformer is like a simple machine. It is a device used to turn large amounts of voltage with low current into small amounts of voltage with high current or vice verse. The power (IV) remains the same, but you can raise and lower voltages as necessary.
