When a resistance measurement is taken from both primary leads tied together to both secondary leads also tied together in a transformer, and the resistance obtained is 200 Ohms -- not safe in my book.
The secondary winding of a double wound transformer is 'floating' in that it is not referenced to any other part of the circuit. You choose how to reference it. You cannot accomplish this without a transformer.
There is no disadvantage with a current transformer -it does exactly what it's supposed to do, that is:reduce the current flowing in the primary circuit to a value that can be handled by its burden (ammeter or protective relay).electrically-isolate its secondary circuit from the primary circuit.
All transformers are magnetic. A transformer is two (or more) coils of wire wound together. The varying magnetic field created by the primary winding induces a current in the secondary coils proportional to the ratio of the number of turns. You're probably refering to a switchmode powersupply as a "electronic transformer" (which is bad nomenclature, by the way). A switch mode supply actually contains a normal transformer in its core, along with circuitry to allow for a wide input fange and a narrow output range.
The difference between a double wound step up transformer and an auto transformer is the double wound on the step up transformer and the single wound on the auto transformer.

The difference between a wound and an injury is that, when injured the skin is torn while a wound is what is formed after the skin is torn.
The difference is between how the windings relate to magnetic material around which they are wound. If this magnetic material surrounds the windings then the device is said to be a shell type transformer. If the windings cover the exterior of the magnetic material then the transformer is said to be of the core type. Please see the link.
they are to convert power into jeremy osborne, which in turn creates an aneesh karan
do exist! Is there a real question about d.w.t's? On a double wound transformer, the primary winding is isolated from and secondary winding, but still use the same common core.

Buy a double wound step-down transformer (230/115 volts) of he appropriate capacity (kva) . You may have to replace the plug on your oven to match the output socket of the transformer if you buy this in England. Do not buy a single wound (auto transformer) as it can be extremely dangerous if it is wrongly connected.Alwyn.
They indicate the laminated metal core upon which the windings are wound.
