You want to know about the voltage selector circuit using transformer?
KAVITAKOLI
the voltage selector circuit is used for converting input electrical energy through the voltage selection circuit,which is arranged within the transformer body with its two ends electric allay connected to an input port and an output voltage connection device must be plugged in a socket portion on the transformer body to initalize a micro control unit through feedback to change a volatage value sent to a voltage transformer unit and in turn change the voltage of output electrical energy until a display device displays an ideal output voltage value. Then, the user removes the connection device, and the voltage value of the input electrical energy is converted into corresponding to the selected

Advantage of a transformer over a transformer coupled circuit?
Sounds more like a "homework" or "test" question, rather than a real-world question, and vague, at that! Could you re-phrase your question in a better, more-precise context, or check it for typos? Right now, your question seems to ask "What's the advantage of using a transformer, instead of using a transformer-coupled circuit?"...which makes no sense, since a "transformer-coupled circuit" USES a transformer.
What is an isolation transformer?
AnswerAn isolation transformer does not have a direct electrical path from the power input side to the power output side. The term is also used to define how much electrical isolation exists between the input and output windings. For example when using line-voltage input transformers to power low voltage device handled by humans, a high degree of isolation is required for safety.Isolated transformers often use separate bobbins for the primary and secondary coil windings, but usually the windings are just wound on top of each other with insulation in between.There is usually an electrostatic shield between windings which is tied to transformer case.Non-Isolated transformers are becoming rare. A common example is the "Variac" which is a non-isolated variable transformer. Usually the term "auto-transformer" is used to describe non-isolated transformers. They are rarely found in consumer products.Although any transformer with a separate primary and secondary winding is an isolation transformer to some extent, The term is usually used to denote a special-purpose transformer built just for that use. It is tested and rated to withstand a very high voltage difference, called the withstand voltage, so that even if thousands of volts are applied to the primary, it will not leak through to the protected side. These transformers are used in the medical industry, to protect patients hooked up to monitoring instruments that are powered by utility mains, as well as other uses.An 'isolation transformer' is a transformer specifically used to electrically-isolate the secondary circuit from the primary circuit. Of course, ALL mutual transformers do this, but an isolation transformer normally has a 1:1 ratio, which means its secondary voltage is the same as its primary voltage. In other words, its purpose is NOT to change the supply voltage, but to isolate the user from the supply circuit.Isolation transformers isolate the secondary circuit from the earthed (grounded) primary circuit. As there is no earth return from the secondary circuit back to the primary supply, isolation transformer eliminate the risk of shock between the secondary circuit and earth.An example of an isolation transformer is a bathroom shaver socket. The output is completely isolated from the earthed supply, so users cannot receive a shock between the outlet and earth.
Introduction of clap switch?
This circuit can switch on and off light a fan or a radio etc;by the sound of a clap This circuit is constructed using basic electronic component like resistor transistor relay transformer capacitor .This circuit turns on light for the first clap . the light turns on till the next clap .for the next clap turns off this circuit works with 12v voltage . therefore a step-cown transformer 12v/300ma is employed. The working of the circuit is based on amplifying nature of the transistor . switching the nature of transistor and relay as an electronic switch.
What is the importance of determining of resistor values?
it is used to check or verify how much current pass through the circuit using voltage source.
Can you measure the continuty using only one end of the wire?
You need to make a complete circuit to test continuity. If the transformer neutral is grounded then you can use just one end of a wire. Measure the wire end to ground will check continuity of the wire. The reading will follow the wire back to the ground point of the transformer there by forming a circuit that can be measured as open or closed. Using this procedure, the power can be shut off and the reading will be taken using the meters power.
Can you give us a circuit of low voltage convert to high voltage?
yes. using step up transformer we can convert low vlg to hi vlg
What is the purpose of a transformer?
It steps down voltage by moving the iron core spacing. Mostly using on high current welding transformer. Easy to achieve changing output voltageand does not need to use high power selector to switch voltage
What is the voltage doubler using charge pump?
What is the math in a voltage doubler without a transformer? how doesa voltage doubler without a transformer?
What is the purpose of using transformer in electric bell circuit?
To supply the bell, because the latter has a rated voltage that's lower than the mains.
What is the maximum DC voltage you could expect to obtain from a transformer with an 18V rms secondary using a full rectifier circuit with a filter capacitor?
25.46V assuming output of transformer is pure sinewave.
What is Core in a Transformers?

What is the maximum DC voltage you could expect to obtain from a transformer with an 18V rms secondary using a full-wave rectifier circuit with a filter capacitor?
25.46V assuming output of transformer is pure sinewave.
What device raises voltage?
Depending on your application... Use a voltage dividor (two resistors) if it doesn't draw a lot of current. You could also try a voltage regulator or using an op amp as a buffer, with the input the voltage you want. That voltage could come from a voltage divider, since op amps draw extremely low current.
What should be the secondary voltage of a transformer needed in a rectifier circuit if the required DC voltage is 6 volts using a?
A little more than 6 volts RMS, or 17 volts peak to peak (can get -6 and +6 voltage this way using a full wave rectifier). The voltage will depend strongly on your design - are you using circuitry that clamps the output voltage to a specific value (you should!). If you are doing this, I would find the cheapest transformer that meets the current capacity you need that has an output near the 6 volts you want.
How do you build a transformer using a battery charger?
Ni-Cd , Ni-HM and other rechargeable batteries are in massive use now a days.Let me not describe the use , importance and bla bla of the rechargeable batteries.What we are going to talk about here is how to make simple battery charger circuit to recharge your rechargeable batteries.Making a battery charger circuit is very simple , Simply step down the mains voltage using a step down transformer and convert the current into DC and stabilize it using a bridge rectifier circuit.But you might not want to use a transformer in your circuit to maker your battery charger circuit small and handy.If you don't want to use a a transformer to step down the mains voltage then you can also use a resistor and a capacitor to step down the voltage and stabilize it.And you can see the circuit diagram of a battery charger below which is not using any transformer.
