How do you calculate the transformer turns ratio?
For an ideal transformer, the voltage ratio is the same as its turns ratio.
What is the difference between ideal transformer and practical transformer?
There are basically 4 major differences :- 1. The windings (both primary and secondary) of an ideal transformer are considered to have zero resistance, hence the transformer is lossless. 2. There is no leakage flux in an ideal transformer. 3. The permiability of the core material in ideal transformer is considered to be tending to infinity and hence the current needed to set up the flux in the transformer is negligible. 4. There is zero hysterisis and eddy current losses in an ideal transformer.
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.
What is leakage current in transformer?
In low voltage and electronics Leakage Current is any current that flows when the ideal current
Describe the meaning of the word ideal as applied to a device or system?
The word Ideal refer to the device or system which has ideal characteristics i.e perfect in every way.
What are performance characteristics of a transformer?
The properties of an 'ideal' transformer are (1) voltage ratio equals turns ration, (2) no losses.
What is the use of ideal transformer?
Ideal transformer is useful in understanding the practical transformer..i does't have losses...
What is meant by the term ideal transformer?
ideal transformer is that which has no power losses.if any transformer transfer power to secondary without power loss then that call a ideal 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.
What happens to the current if the potential difference is stepped-up in an ideal transformer?
In an ideal transformer, if the voltage is stepped up by a factor of x, then the current is stepped down by a factor of x. The end result is that the power, P=VI, is not changed. Again, this is in the ideal case.
Does a transformer convert mechanical energy to electrical energy?
No. A transformer doesn't source or sink energy, or convert energy from one form to another.The ideal transformer merely changes the parameters of an electrical current, with no effect on energy levels.A non-ideal (real-life) transformer decreases the energy in the electrical circuit, because its lossesrob some of the energy and turn it to heat.
Why transformer is not called an amplifier?
In an ideal transformer the power in equals the power out there is no gain. In an ideal amplifier the power out equals the Gain *Power In. An ideal transformer transforms energy at a ratio of its windings. For example an ideal 1:10 ratio transformer (step up) would convert a 10Volt input at 10amps to a 100Volt output at 1Amp. Or conversely an ideal 10:1 ratio transformer (step down) would convert a 10Volt 10Amp input into a 1Volt 100Amp output. Since Power = Voltage * Current we can see the power in equals the power out in an ideal transformer. In an ideal amplifier the power out is greater than the power in. This is defined as the gain of the amplifier. An ideal amplifier with a Voltage gain of 10 would take a 1Volt 1amp signal and amplify it into a 10Volt 1 amp signal. An ideal amplifier with a Current gain of 10 would take a 1Volt 1Amp signal and amplify it into a 1Volt 10 amp signal. Since Power = Voltage * current we can see the power in is less than the power out showing a gain in power.
