force in the primary will permit the necessarycurrent to flow through the primary coil. This requires that thecoils of the transformer shall have as little resistance as possible,and that the primary and secondary coils shall be wound closetogether, so that no perceptible portion of the magnetic… … Fig. 208. Diagram of Connections of Constant-VoltageTransformers in Parallel specially designed to realize these two conditions is sometimescalled a consiant-potential or constant-voltage transformer. A constant-voltage transformer is necessary if it is desired totransform a given voltage in a…
