By using step-down transformer
if you drove the 18V winding with 230V the transformer would burn out, if it didn't catch fire first
no, the transformer is much more efficient <><><> HOWEVER- a transformer only changes the voltage of AC current- it does not change it to DC. You will still need diodes or rectifiers. You can also use a motor/generator- a 230v AC motor turns a 12 v DC generator.
You need a step up transformer unfortunately. Buy an Ugly's book electrical reference book. They're great and there is a transformer chart in there that will list the proper size or Kva that you will need according to your amperage need.
since the iron loss depends only on the volage and frequency,the supply volage is 230v ac.Hence iron loss is always constant
You can get a transformer that converts the UK's 230V power to 120V, but you cannot get a transformer that will convert from 50Hz to 60Hz. Often, US equipment can work, except that they will work hotter and less efficiently on the 50Hz power. Consult your clipper and trimmer documentation - you may find that it will work just fine on 50Hz.

NO
The higher voltage it transformed to a lower voltage by the use of a step down transformer.
Why are you asking someone to do your homework for you? Ask your teacher.

If you exceed the rated voltage of your transformer, there is a high possibility that its insulation will break down and you will ruin that transformer.
You need to use a 2:1 ratio transformer, with a capacity (in volt amperes) to match the load you have in mind.
It is not advisable because the motor would run 20% faster which might produce damaging overpressure in the thermal circuit.
Yes, if the device has a built in step down transformer. Think of it this way, the electricity in your household is a typical 230v. Mobile phones tend to use 6v of electricity. So when you plug your phone charger into the wall socket, 230v will run directly into that charger, through the cable and into your phone, typically blowing up the device or overloading it. That's why the charger has a transformer in it (a step-down transformer) which steps down the voltage from 230v to about 6-12v. So hopefully that explains your question. If not, try to eleaborate a bit more so i can possible help further. Thank you.

ya. we are using diode in a battery charger to convert ac into dc. 230v dc is step down by using step down transformer
Using Ns=(Np*Es)/Ep =(500*12)/230=26 turns
