Transformers neither generate nor draw electricity. They either step down (most common) or step up the voltage between the source (generation) and load. The cycling collapse of the primary winding either induces a greater or lesser voltage in the secondary winding, depending on which has the most turns of wire.

Can you use number of appliances on a single transformer?
You can use multiple appliances as long as long as you don't draw more current than the transformer can supply.
How many amps does a 3 kva transformer draw?
The primary current of a transformer depends upon the secondary current which, in turn, depends upon the load supplied by the transformer. There is not enough information in the question to determine the rated primary and secondary currents of the transformer.
What is an ideal transformer Draw the no load phasor diagram of transformer?
Resistance ideal transformer is the one having no core losses, infinite permeability no mmf needed to set up flux), windings are having no resistances or reactances.

How do you draw phase diagram for transformer operating at load with lagging PF and leading PF?
In order to draw the phase diagram for transformer operating at load with lagging PF and leading PF, you will need to know the equation for the transformer being load free. This constant will help you with the load bearing equation of Np/Ns=Vp/Vs=Is/Ip.
Does transformers draw any current when secondary is open?
-Yes, the transformer draw current when secondary open. Because, the secondary of the transformer is open, the primary draws only no-load current, which will have some copper loss. Therefore, power is no longer transferred from primary to secondary in this approximation, and negligible current goes through the secondary windings.Some current will flow through the primary as well as secondary to magnetise the core to maintain the internet relaship between primary &secondary winding as the winding consist of small resistance it is neglected practically hence the current will at at no load also which is small in magnitude compared to the full load current.Thta is why we says that transformer draws current when secondary is open.
How much does wave technology cost?
Th generation of electricity using the movements of waves comes in several different forms. One form has floating units on waves inside Territorial waters. This form has several segments that move up and down with the waves and generate electricity from that movement. The other form has a tube attached to a cliff face with the lower part under the surface of the water. Tidal rises and falls draw air into the tube and generate electricity. Depending on which form you use and how large it is will tell you how much it will cost
How does electricity reach our homes?
Through electrical cables, which can be overhead or underground. The local cable is normally a 415-volt three-phase cable providing each house with a single-phase 240 v supply. It is normally fed from a transformer which takes it power from a higher power cable working at 11,000 volts.
Can resistors be used to use a 110 volts rated hairdryer in a 220 volt source?
Resistors could be used if you can find resistors with a high enough wattage rating to dissipate the heat that they will generate. Your best bet is to purchase a voltage adapter. The adapter is just a transformer that steps down the voltage from 220 to 110 volts. Locate on the hair dryer what the wattage draw is and then match the transformer (adaptor) to that wattage output.
How do you find the maximum amp draw on a step up transformer?
It depends on the load. A good transformer has over 90% (some as high as 99%) efficiency. So the power drawn by it is a function of the power in the load, plus a small amount due to losses in the transformer.
