∙ 9y agoWhat allows it is the use of alternating current. The simplest transformer has two separate coils of wire on a magnetic core. A supply connected to the primary coil or winding causes an alternating magnetic flux in the core, and this flux induces a voltage in the secondary winding. The output voltage is set by the number of turns in the secondary winding.
The number of turns in each winding is set by the turns-per-volt figure, which depends on the amount of magnetic flux, which in turn depends on the size of the magnetic core. A large core used in a power transformer could have a turns-per-volt figure of less than one, so it's measured in volts per turn.

How current transfomer is step up voltage transformer n step down current transformer?
Current transformers are not voltage transformers. Current transformer are used for metering or protection purposes, with single turn primary. Generally the secondary current is either 1Amps or 5Amps.
Is a three dB difference in sound twice as loud?
No, 10 dB is perceived to be twice as loud, and requires 10 times the power.Doubling of the volume (loudness) should be perceived by a level difference of 10 dB − psychoacousticians say.Doubling the sound pressure (voltage) level corresponds to a measured level change of 6 dB.Doubling of acoustic power (sound intensity) level corresponds to a calculated level change of 3 dB.Scroll down to related links and look at "How many decibels (dB) is twice (double, half) or three times as loud?"
Why are ID cooling towers preferred in utility plants?
to cool what ever they are burning down
Which manufacturing union staged a series of sit down strikes in 1937?
united auto workers
What is the meaning inverted position?
Inverted position means the object was turned inside out or upside down.
What allows simple transformers to step up or down?
The voltage ratio in transformers used in power supply is set by the ratio of the number of turns on the primary and secondary windings.
What the different between voltage generators and voltage transformers?
Generators generate and transformers step up or step down the voltage
What allows simple transformer's step voltage up or Down?
unequal coiling of wires
What are transformers designed to operate with?
to step up voltage or to step down voltage
What are the disadvantages of step down transformers?
There are no disadvantages to either step-up, or to step-down, transformers. They do exactly what they are intended to do: change voltage levels while maintaining approximately the same power level on both primary and secondary sides.
Why you use transformers to transfer power?
Transformers do not exactly transfer power, they either step up voltage or step down the voltage from one source to another to make it a useable voltage.
What happens to voltage in a step-down transformer?
The voltage induced into the secondary winding will be lower than the voltage applied to the primary winding. The primary winding being the winding connected to the supply, while the secondary winding is the one connected to the load.
How do transformers reduce electrical voltage?
This type of transformer is called a Step-Down transformer. All transformers have an input to output ratio. The transformers that increase voltage are called Step-up, and the transformers that protect against surges are called unity gain. The Unity gain transformer has a 1:1 ratio and provide a mechanical way to isolate a source of voltage from a load.
Device used to step voltage up or down?
As transformers do not work with DC., the answer is a voltage divider network (step down) or a voltage multiplier network (step up).
Which part of the process of distributing electricity changes the voltage of the current?
The transformers step-up and down voltage for transmission and use.
What are at least 2 types of electrical transformers in science?
A variety of electrical transformers are produced for a variety of purposes. All of the types use the same principle discovered by Michael Faraday, and employ many of the same parts. The various types include. Audio transformers, Instrument transformers, Pulse transformers, Power transformers, RF transformers. .
How are step-up and step-down transformers used in the transmission of electric current from the electric company to homes?
(This is what my teacher said, I wrote this down in my notes) The answer is, Step-up transformers are used to increase the voltage of an electric current before it is sent out over transmission lines from the electric company. Step-down transformers are used to reduce the voltage of current from high-voltage transmission lines before it enters homes and businesses. Some devices, such as televisions, contain step-up transformers that increase the voltage once again.
