Transformer Wire Length Calculator

Find the length of the wire based on the number of turns in the coil and the perimeter of the bobbin.

The length of a wire does not significantly impact the current, but it can have a noticeable effect on the voltage distribution along the wire, especially when the wire is supplying a significant load in the middle or at the end. Utilize the transformer wire length calculator to determine the total length of a wire in a transformer. By inputting the number of turns in the coil and the perimeter of the bobbin, you can calculate the total length of the wire.
