Transformers use magnetic induction between 2 coils of wire to produce a voltage in the secondary winding. Typically the main purpose of a transformer is to step up or down the voltage by having differing number of windings between the primary and secondary coils. A secondary effect is to keep the 2 systems electrically isolated from eachother. If one of the phases becomes grounded, the ground is only seen on the portion of the system downstream of the transformer, thus increasing relibability.

Why do we study theory computation?
a computer is what?? it is simply a machine made of hardware??but why we need computer....the answer is we need computer to perform computation on a specific task....how this computation will occur in the computer is defined by a set of rules ...to understand these rules ,we need to study theory of computation.... theory drives practice and practice drives theory....to make efficient machines for computation tasks we need to study theory of computation.
Which theory compares light movement to dropping a pebble into a pond?
The theory of comparing light movement to dropping a pebble into a pond is called light refraction.
What is quarts theory?
Actually it is spelled with a "z"...quartz theory. I think you may be referring to Quartz Crystal theory. When the metals described on the periodic table of the elements come into contact with each other or are changed by chemical reactions in a lab, their properties can be drastically altered. The crystal theory explains why these property changes occur and helps scientists predict exactly which changes will happen.
Where is the solution of Elements of the Theory of Computation?
nowhere

What referred to the theory of isolating or resisting the spread of communism?
containment
What is the elementary theory of an ideal transformer?
A transformer can never be an ideal device to transfer power. Its inherent design has limitations caused by losses WITHIN the device itself.
How do you make 2v transformer in to a 9v transformer?
In reality there's no way to do that that'd make sense. In theory you could rewind the 2nd winding to get a higher voltage.
What has the author J Pirenne written?
J. Pirenne has written: 'General theory of oscillatory phenomena in transformer winings'
Should you be on your MacBook when in storm?
If it's a lightning storm, Your laptop is powered by an inline transformer as part of the power cord so, in theory,if lightning hits your house it will destroy the transformer first before hitting your laptop.At the very least, in theory, if you lose power in any storm, a power surge from the power being turned back on hits your transformer and destroys it first and not get as far as the laptop.Either way you can't be hurt from a storm just by using your laptop if your NOT connected to the power cord if your in your house or building.
What is current trandformers?
I believe you meant transformer. If so it is a transformer used in high voltage circuits to reduce the current to a safer measurable value. It can be used as a direct input to a metering or protective relay to covert high currents to a lower value. It is used in AC circuits and typically encircles the conductor(s) it is monitoring, then works by using the expanding/ collapsing field which is the theory of induction used in transformer operation. It is the primary side of a "transformer" which only works when there is current flowing through it.
What did Koch contribute to biology?
he became famous by isolating Bacillus anthracis ( 1877 ) the tuberculosis bacillus ( 1822 ) and the vibrio cholerae .Edit:Robert Koch was instrumental in modifying the scientific method to prove that a given pathogen caused a specific disease. He was the first to discover that bacteria are responsible for causing diseases, and the theory was called Germ theory of disease.
Which scientist proposed a link between contaminated water and cholera?
It was a doctor, John Snow, in London England, during the cholera outbreak in 1853. Those that drank beer, were free of the plague. Isolating a contaminated water pump, proved the theory.
Why percentage differential protection is preferred over differential protectionfor internal faults?
if we are seeking for internal protection of transformer only, then if any external fault occurs then it will show the fault though it should not. what a percentage differential protection will do means, it will include a restraining coil which is excited by the current in the transformer itself. Also the percentage differential relay ha taps. So it is easy to avoid the external fault. for reference check 'theory and applications of transformer differential protection' by GEORGE W.McKENNA, AIEE transactions 1950,volume 69
How do you measure no-load current in a stabilizer?
Measuring No-LoadIn theory the no-load current of a transformer is zero. But in practice there is iron loss and core loss in the transformer, so there is power loss. Connect an ammeter in series with the stabilizer to measure the no-load current. Check your energy meter at no-load to see how much power is consumed. Ohms law: I(Amps) = E(voltage) divided by R(resistance). In the case of coils (transformer), the resistance of the coil would simply be the total impedance (Z). If I am remembering this correctly, you get, I=E/(R+Z)
Why is the world different because of madame curie?
Madame Marie Curie's achievements include the creation of a theory of radioactivitytechniques for isolating radioactive isotopes, and the discovery of two new elements, polonium and radium. It was also under her direction that the world's first studies were conducted into the treatment of cancers, using radioactive isotopes.
What is the current in the secondary coil fi the current in the primary coil is 5.0A 10 loops on primary coil and 20 on secondary coil?
If I am not wrong then you have asked about a transformer. And its a current transformer. By theory of voltage transformer we know that Vs/Vp = Ns/Np So for answering your question we need the value of number of turns in primary and secondary coil. But you can use this equation to find your answer if you have other values. By using ohmic law you can convert voltage to current.
