This app is very lightweight and super easy-to-use app!! the user interface is super easy. Using this app you can easily calculate dozen of things as mentioned below list.

1. Calculate Primary & Secondary Windings for Rated Current and Voltage.
This app calculates the total number of primary and secondary windings turns for a given voltage and current rating.

2. Calculate Primary & Secondary Wire Size(mm) for Rated Current and Voltage.
Also, this app will calculate the size of primary and secondary wire (mm) for a given primary/secondary current and voltage.

3. Calculate How Many Parallel Primary-Secondary Wires, That You Have in Your Home, are Needed for The Rated Primary-Secondary Current and Voltage
In this app, there is a special section, where you can enter the primary and secondary wire size(mm) that you currently have in your home and this app will calculate for you, how many parallel wires you need for your primary/secondary windings for your given home wires.

4. Calculate Voltage Per Turns
This app also provides you the Voltage Per Turns (VPT) for your Ferrite transformer w.r.t your given data.

5. Verify Your B-max Each Time
Using this app you can also verify the B-max of your last calculated Ferrite transformer data.

6. Calculate Cross Sectional Area of Different Cores
By using this app you can easily calculate Cross Sectional area (AE) of all types of E cores [R, I, E] and also can calculate the cross-sectional area of a Toroidal Core.
