Okay kiddo, do you know what a transformer is? It's a machine that helps in changing electrical energy from one level to another level. For example, it can change high voltage into low voltage or low voltage into high voltage.
Now when we add "parametric" to transformer, it means we are adding an extra feature that allows us to adjust or change the parameters of the transformer.
Think of it like playing with blocks. You can make a tall tower or a small one by changing the number and size of the blocks. Similarly, with a parametric transformer, we can change things like the voltage, current, and frequency by adjusting the parameters like the size and shape of the coils or the amount of core material used.
This feature allows engineers to make transformers that are custom-made to fit specific needs or situations. It's like having a power tool that can change its shape and power depending on the job that needs to be done. And that's how a parametric transformer works, in a nutshell!
