Transformer Wire Length Calculator

The length of the wire doesn't practically have an effect on the current, but it has a considerable effect on the voltage profile across the wire provided that the wire is feeding a considerable amount of load in the intermediate path or at the extremity. Use the transformer wire length calculator to find the total length of a wire in a transformer. Calculate total length of a wire based on the number of turn of the coil and the perimeter of the bobbin values.

Total Wire Length = Number of Turns × Perimeter of Bobbin


Calculate the total length of the wire in a transformer whose number of turns is 25 and the perimeter of the bobbin is 50mm?


Total Wire Length = 25 × 50
= 1250 mm
