The transformation ration for a transformer is (Vs/Vp) = (Ns/Np).
Which means, Voltage ∞ No. of turns.
So, we can say if we have to increase voltage, then we have to increase the no. of turns, and as the no. of turns increase the space between the core and the winding reduce.
So, from above we can say that the HV windings are closer to the core than the LV windings.
AnswerThere are two configurations for windings in Transformers.
The first is called 'concentric' or 'tubular', in which the low-voltage windings are placed innermost (i.e. closest to the core) with the high-voltage windings outermost.
The second is called 'sandwich', in which the windings are arranged in ring bundles, with alternate rings of high- and low-voltage windings placed one above the other.
The first configuration is used with 'core' type cores, with half the LV/HV windings placed around one limb of the core, and the other half of the windings placed around the second limb. The second configuration is used with 'shell' type cores, with the ring bundles placed around the centre limb.

What is the voltage output if the transformer is connected backwards?
It doesn't really matter which way around you use a transformer, the primary winding is ALWAYS whichever winding you connect to the supply, and the secondary winding is ALWAYS whichever winding you connect to the load. For either connection, the turns ratio will ALWAYS equal the voltage ratio for an ideal transformer (or close enough for a real transformer).
What multimeter readings set to measure resistance indicate an open circuit and short circuit in the primary and secondary windings of a mains power transformer. And what readings show good?
You cannot use an ordinary multimeter to assess the difference between a normal power transformer winding and a shorted power transformer winding. You need a Q meter and/or to power it up at a reduced voltage with limited current to see what happens. Note that a shorted power transformer is capable of exploding, so you need to take appropriate safety precautions.
Conversion of 2-winding transformer into auto transformer?
Yes, you can use a mutual (2-winding) transformer as an autotransformer, by connecting the two windings in series. For example, if you have a 240:120 V transformer, connecting the two windings in series and supplying the 240-V winding with 240 V can give you a secondary voltage of 360 V. But you must take into account the polarity of the transformer, and realise its capacity will change.
In what type of situations we use the capacitor in between primary and secondary winding of transformer?
HID lights is where I have seen that application although I do not understand why it is put there, instead of parallel with the load.
How could you convert step up transformer into step down transformer?
Injecting power into the higher voltage winding of a transformer will make it act as a step down transformer; injecting power into the lower voltage winding will make it act as a step up transformer. A transformer can be used both ways.

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.
What function does a capacitor serve in an auto transformer?
An autotransformer does not normally use any capacitors as it is a transformer with one winding and the lower voltage is taken from a tap part-way up the winding. A capacitor could be added if there is a concern about the power factor presented by the autotransformer to the supply.
What is the voltage output if the transformer is connected backwards?

Why doesn't the primary winding on a transformer have a neutral?
In a three phase transformer, the primary winding is often configured in a Delta. The delta winding configuration does not use a neutral. The secondary winding is often in a Wye configuration, which does have a neutral. The Delta configuration is typically used for transmitting power to various locations, and thee phase loads where a neutral is not needed. The Wye configuration is typically used to distribute power in a facility where there are single phase loads that need a neutral. There are other reasons to use either Wye or Delta, such as grounding issues, but I think the short answer is probably what you're looking for (I hope). Hope this helps! Dave
