ƒ Wingdings may be connected in series to obtain their combined voltage when properly phased. Current will be equal to the current of the lowest winding. Example: Two 6.3 V
windings @ 2A in series would be 12.6 V @ 2A. Wingdings may also be connected in parallel to obtain combined current. Example: Two 6.3 V windings @ 2A in parallel would
be 6.3 V @ 4A.
