How do transformers work since the two coils aren't connected to each other?

The AC - and it must be AC - in the primary coil generates an alternating magnetic field around the coil; this alternating magnetic field induces a current in the secondary.

What is SIC 3677?
Radio frequency or voice frequency electronic transformers, coils, and chokes are classified in SIC 3677: Electronic Coils, Transformers, and Other Inductors.
Is varnish a good conductor of electricity?
No. In fact it is used as an insulator.The copper wire, used in transformers and other similar wound coils, are coated in varnish, to act as an insulator between each wire.
Why are rectangular coils used in power transformers?
Transformers are used to step up and down voltages. The amount of this step is directly proportional to the turns ratio from one winding to the other. Using circular coils means a minimum amount of copper can be used, since the number of coils is relatively fixed by the voltage levels involved. Another reason is corners are not a good idea when dealing with really high voltages - they can result in eddy currents, strange flux paths, corona, and localized heating to name a few problems.
What is a y configuration on a 3 phase circuit?
On a wye connection all three ends of the phase winding coils are connected together and grounded. The other end of the three phase winding are connected to the supply voltage.
What are the two types of transformers?
The two general categories of transformer, based on their construction, are (a) mutual transformers and (b) autotransformers.Mutual transformers have two coils, or 'windings', termed the primary (input side) and the secondary (output side), which are electrically isolated from each other, being linked with a magnetic field.Autotransformers have a single, shared, winding and so, do not provide isolation between the primary and secondary sides.Mutual transformers can be further classified, according to their function: e.g. power transformers, distribution transformers, isolation transformers, instrument transformers, matching transformers, etc.
What does the inside of a 3 phase transformer look like?
A three phase transformer has three primary coils and three secondary coils wound on a laminated iron core shaped like the capital letter 'E'. Each pair of primary and secondary coils are wound concentrically onto each leg of the 'E'. There is a straight , laminated core segment, that connects across all three legs of the 'E', forming a circuit path for the magnetic flux. The primary and secondary coils can be arranged as an autotransformer, with the primary and secondary coils connected end-to-end, with a common conductor tapped at the interconnection, or as separate coils with two separate connections for each coil.
What is sumpners test?
Type your answer here... This test provides data for determining the regulation, efficiency and heating under load conditions and is employed only when two similar transformersare available. One transformer is loaded on the other and both are connected to the supply. The power taken from the supply is necessary for supplying the losses of both transformers and the negligibly small loss in the control circuit. The primaries of the two transformers are connected in parallel across the same a.c supply. With the switch open, the wattmeter reads the core loss for the two transformers. The secondaries are so connected that their potentials are in opposition to each other.
Is there going to be any other transformers?
Yes There Will Be a Transformers Released In 2014 Called Transformers Rise Of Galvatron
Does a 2000 suzuki esteem 1.8 have 4 coils?
Two coils two spark plugs are under the coils and the other two are next to the coils
Why are Transformers called Transformers?
Because they can Transform in to cars and planes and other things.
What is the difference between transformers and adapters?
A transformer is a component that changes AC current from one voltage to another. A transformer consists of two coils, one connected to the input, and one connected to the output. A transformer can convert voltage up or down, depending on the number of windings on the coil. An adapter MAY include a transformer to change the voltage, but an adapter usually changes the voltage AND converts from AC to DC as well, and may have a regulator that locks the voltage to prevent a surge and other components that prevent what is called "ripple".
Did Bulkhead die in Transformers?
Movies: Bulkhead was not in any of the Transformers movies as of yet. Prime: He did not die in the animlated series Transformers Prime Sorry but I am unsure of the other Transformers series.
