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 the advantage of bistable multivibrator using 555 ic over those made with opamp or bjt?
The advantage is most of the circuit has already been connected up for you and you only have to add a dc power supply and couple of components to set what frequency you want it to work at.
How RC coupled oscillator is phase shift osillator?
The resistor allows a slow charge to enter the capacitor. When this charge reaches a certain point the circuit activates and forces the capacitor to discharge. Once discharged the circuit reverses itself and starts the charge over again. The larger the cap and/or resistor the lower the frequency because it takes longer to charge the cap.
When a PNP transistor is connected in a circuit it can be used as a power amplifier because?
A PNP transistor has no advantage or disadvantage over an NPN transistor in its ability as an amplifier. Rather, the current-handling capacities of the transistor determine if it's usable as an amplifier.
What Advantages of double tuned amplifiers over single tuned amplifiers?
The primary advantage of a double tuned amplifier, such as, an amplifier with a tuned circuit on the input and the output, is narrow bandwidth. Another advantage to the circuit is impedance matching with the previous stage, etc. And last but not least your double tuned amplifier will have more gain for electrons spent getting the job done. In our battery operated everything world that is an important design factor.
What is your edge among the other contestants?
It is to have an advantage (edge) over an opponent.
What are the advantages of double wound transformer over a auto transformer?
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.
What is advantage and disadvantage of bridge circuit over center tape circuit?
Advantages: No need of centretap transformer Low cost Disadvantages: It require 4 diodes Peak inverse voltage is high
What are the advantages of 3-phase transformer over 3 single-phase banks of transformers?
The main advantage is that the 'footprint' of a three-phase transformer is smaller than a transformer bank, and all connections are prewired which makes them easier and quicker to install and replace.
What is the advantage of using the bridge rectifier over the conventional full wave circuit?
Output voltage is higher!!!
What are the Advantage of mosfet over fet?
MOSFET has high input impedance and offer input signal isolation from the circuit
What is the advantage of a parallel circuit over a series circuit.?
In a parallel circuit, all the external resistors are supplied the same potential difference which is not possible in a series circuit. Also in a parallel circuit, every resistor or component can be individually turned on or off without affecting the rest of the circuit.
Advantage and disadvantage of RC coupled amplifier?
Electrical Engineering It has a wide frequence response .the gain is constant over the audio freq range which is the region of most important for speech music
Why a two winding transformer is used instead of single winding transformer?
You need two windings because that is the purpose of the transformer - to convert one voltage into another. If there were only one winding, it would be an inductor, or a special case called an autotransformer, but that is still "sort of" two windings.AnswerThe major advantage of a two-winding transformer (a 'mutual transformer') over a single-winding transformer (an 'autotransformer') is that a two-winding transformer provides electrical isolation between the secondary and primary circuits. This is very important for safety reasons and there are many circumstances in which the use of an autotransformer is not permitted.
Can i Over load an oil filled transformer?
Any transformer can be overloaded by applying a load above the capacity rating of the transformer.
How did Nikola Tesla make circuits work?
Tesla arrived in the United States in 1884, at the age of 28, and by 1887 had filed for a series of patents that described everything necessary to generate electricity using alternating current, or AC. To understand the significance of these inventions, you have to understand what the field of electrical generation was like at the end of the 19th century. It was a war of currents -- with Tesla acting as one general and Edison acting as the opposing general. A Tesla coil is a type of resonant transformer circuit invented by Nikola Tesla around 1891. It is used to produce high voltage, low current, high frequency alternating current electricity. A Tesla coil transformer operates in a significantly different fashion than a conventional transformer. In a conventional transformer, the windings are very tightly coupled, and voltage gain is limited to the ratio of the numbers of turns in the windings. However, unlike a conventional transformer, which may couple 97%+ of the magnetic fields between windings, a Tesla coil's windings are "loosely" coupled, with the primary and secondary typically sharing only 10-20% of their respective magnetic fields and instead the coil transfers energy (via loose coupling) from one oscillating resonant circuit (the primary) to the other (the secondary) over a number of RF cycles.
What is a variable transformer?
A variable transformer is capable of changing its output voltage from 0 to maximum output or over a specific range. It is also named an adjustable transformer.
Is it dangerous to run an appliance with more watts than the transformer?
A transformer has a rating that is usually expressed in KVA. This is approximately a wattage rating. It is not dangerous but it can be the cause of some concern. An appliance has a set current that is draws. This current times the voltage is the appliance's wattage. The same goes for the transformer. It only has a certain capacity to supply a specific current that is governed by its KVA (watts). Driving the transformer beyond its rated capacity tends to heat the transformer beyond its working temperature. If left in this over current draw the transformer's windings insulation will break down and the windings will short circuit. This is usually the end of a working transformer. So short answer, more watts (amps) from appliance equals burned out transformer.
