Transformer is a electric device which it can be used for to transfer the ac current one circuit to another i.e. To reduces voltage and without frequency changing. Many types of transformer available in various purpose i.e. Stepup transformer, stepdowntransformer ,autotransformer ,,,,,,,etc answered by arivukkarasu.a

How do you convert car battery into 220 w electricity?
use a transformer.
Can a 5.8 ampere 110V run on a step up step down 300 W transformer?
No because the load is 638 VA which is too much for the transformer.
What is the function of intermediate frequency transformer?
intermediate frequency transformer (ift) acts as a band selective n/w. the ift which is 455 khz is then given to IF amplifiers which is then given to detector.
If increase load of secondary side of transformer. why primary side current increases?
The wattage must remain equal on the primary and secondary sides of a transformer. An example to the above statement with a 1000 watt step down transformer. To fine the watts (load) the formula is W = A x V. The primary side of the transformer has the capacity of 1000 W = 4.16 Amps x 240 Volts. The secondary side of the transformer has the capacity of 1000 W = 8.3 Amps x 120 Volts. Using the transformer to its maximum, without overloading it, the primary will be 4.16 amps at 240 volts and the secondary will be 8.33 at 120 volts. As you can see the wattage (load) remains constant only the voltages and current change.
What is hysteresis angle in transformer?
Generally th e current drawn by the transformer in no load condition is being utilised by the iron losses and the angle b/w voltage and current is known as hystresis angle.
7200 volt 25kw transformer how many amps at 240 single phase?
The formula you are looking for is I = W/E. Amps = Watts/Volts.
Can you run a 1500w power tool on a 3kvA 240W to 110W step down transformer?
I think you mean a 240 V to 110 V (volts, not watts) transformer! Providing your power tool is rated at 110 V, the answer is yes, because its power rating of 1500 W is well within the capacity of a 3-kV.A transformer.
What is a half transformer and a half transformer?
a hole transformer
How should I calculate this. A single phase transformer is rated at 99kVA The primary voltage is 6.6kV and the secondary voltage is 220V Assume no losses and calculate The full load primary current?
First find the ratio of the transformer. 6600/220 volts. Second find the secondary current, I = W/E, 99000/220. Third divide the secondary current by the transformer ratio. The answer will be the primary current. To check your answer (W (or VA) = V x A) multiply the primary current times the primary voltage and the secondary current times the secondary voltage and they should both equal the transformer's kVA.
Why induction transformer called rotating transformer?
Transformer has windings
Can you use ordinary transformer in place of auto transformer?
yes we can place auto transformer in place of original transformer
a transformer supplies electricity to a factory it changes the supply voltage from 1000 w to 440 w which is suitable for factory use the current passing to the secondary bomb is 200 A Calculate the current passing to the primary bomb?
a big banana
