What major design limitation characterized the transformers developed by Lucien Gaulard and John Gibbs?

Answer

They utilized open magnetic circuits

While earlier designs by Gaulard and Gibbs represented steps toward practical power distribution, they relied on open magnetic circuits. This design was less efficient at coupling magnetic flux between windings than the closed iron core design later perfected by William Stanley Jr., which ultimately became the standard for modern transformers.
