Audio Transformers
Conversely, a transformer with a turns ratio of 1:2 would be called a step- up transformer since its secondary voltage would be twice that of the primary. Since a transformer does not create power, the power output from the secondary of an ideal transformer can only equal (and in a real transformer only be less than) the power input to the primary.
Transformer Bushings: What You Should Know About
Three-Phase Transformers: Three-phase transformers can have a different number of bushings based on their configuration. A common arrangement is for each phase to have two bushings—one for the high-voltage winding and one for the low-voltage winding. Therefore, a three-phase transformer might have six bushings in total. Auto-Transformers:

$begingroup$ One flaw of your statement is "a common electric field" if the plate spacing on C1 is sufficiently small vs. the size of the plates the E-Field in the interior of C1 will not be unduly influenced by the main E-field. The total field will be influenced by fringing especially since the presence of a conductor forces a iso-potential. Even if you put a block of dielectric in the ...
