What is transformer w?
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 a transformer is very useful in ac supply?
Transformer is the only device which is capable to stepup or stepdown an ac signal. That's why its used widely in ac supply.
Why not stepup transformer is not used in rectifiers?
Rectifiers turn A/C into D/C, but transformers can only run on A/C.
What is stepup transformer?
A step-up transformer produces a voltage across its secondary winding which is higher than its primary winding. The secondary winding is connected to the load, while the primary winding is connected to the supply.
What is the difference between step up and step down?
in transformers for instance a stepup transformer does exactly that, steps up the voltageAND/OR theamperage and a step down transformer reduces the same. if you have a machine that operates on say 120 volts alternating current single phase and your building or power supply in your buildingis set up for or delivers480 volts alternating current-three phase you will need a step down transformer to operate the machine.

Can you use a step up transformer on a 110 and safely power a cooktop that requires 220?
Generally,no, you can't. Most 110-volt outlets provide only a limited amount of current, normally in the range of 15 amps (maximum). In that case, the maximum power output of the outlet is about 1800 watts. Most 220-volt cooktops I've seen require twice to four time that amount of power, with some power requirements reaching 12 kilowatts (12 kw or 12,000 watts). But these large power users are mostly 36" induction cooktops.In the case of attempting to operate a 220-volt cooktop on an "standard" 110-volt electrical with a stepup transformer, the outlets you have could not begin to provide the required power. If you do the math, you'll find that even attempting this is a very bad idea. Consult an electrician for conformation. No professional electrician would even submit a bid to you to do this job (powering a 220-volt cooktop from a 110-volt circuit with a stepup transformer). They'd tell you over the phone that it isn't something that will fly past the electrical code.
Why are transformers necessary?
Transformers are necessary to stepup or stepdown voltage levels so that transmission of power is convenient. without stepup/stepdown voltage level according to our requirement losses will be very high and transmission and usage of power is not feasible.
Which amplifier converts millivolt to volt?
to convert a 100mv to 1volt u will have to multiply it by 10. so u will need a stepup amplifier to do that. u can depend on am op-amp based amplifier to do it if u r allowed to use external supply, else u will need a transformer for the same. Ashish.K
Why stepup transformer uses ac?
Confusing question! If it is, why transformers use ac? Then it is, for induction there must be change in flux linkage which is possible with ac which frequently changes polarity. In dc there wont be any change. If que is, why step up is used? There will be considerable voltage drop with distant transmission. For this reason step up voltage is required with step up transformer. Since, in high voltages this drop is negligible or efficient transmission
What does a step up transformer increase?
Power is normally transmitted at high voltage through step up/step down transformers to minimize the power losses in the transmission lines (this is one reason anyway). Since power loss is equivalent to the resistance of the conductor times the current squared, stepping up the voltage by a factor of two cuts the transmission losses by a factor of (2^2 = ) 4.
Does Jones chopper is a stepup chopper?
Jones chopper is known as voltage commutated chopper...it is one type of chopper..
