The input waveform from a transformer is altered from a pure sine wave because the load is not purely resistive, meaning in this case that it is not "continuous". Many loads do not pull current "all the time" during each line cycle. A power supply, for instance, only pulls current when the filter capacitor is being charged by the rectifier. This is because the rectifier biases on to charge the capacitor to the peak value of the input waveform, then the capacitor discharges at a rate dependent on load while the rectifier is biased off, until the voltage intersects the next rising input wave. This means the current load on the transformer is actually pulsing on and off. (This is true for both linear and switching power supplies, although you can reduce the pulsing with appropriate inductance in the filter circuit and a more complex design.) Since the AC supply is not "perfect", i.e. having a Thevanin equivalent series resistance of more than zero ohms, along with cables that do not have zero ohms, along with Transformers that are not "perfect", this pulsing current induces a pulsing deviation in the input AC waveform. This effect can be observed even without a transformer in the circuit, but transformers make it more measureable, because the transformers introduce additional "inperfection".

What are the key principles of deterministic programming and how can they be applied to ensure predictable outcomes in software development?
Deterministic programming is based on the principle that given the same input, the program will always produce the same output. This ensures predictability in software development by eliminating randomness and ensuring consistent results. By following key principles such as avoiding side effects, using immutable data structures, and writing pure functions, developers can apply deterministic programming to create reliable and predictable software systems.
What is the best PC tablet?
In terms of value for money and quality, the ASUS eee pad transformer is considered the best, with a price of about £350 (without keyboard dock) and a Nvidia Tegra 2 chip, it is a decent tablet to have. It has very good tech specs and the opportunity to have a keyboard dock. In terms of pure power, probably the soon to come ASUS eee pad transformer Prime. It is not released yet, but it has the same functions as the transformer, but with a quad core processor, rather than a dual core one. It is thinner and lighter, with higher specks. For the moment though, most of the high end tablets have dual core technology, so any of them will be fine. The main ones being the samsung galaxy tab 10.1, motorola xoom, LG optimus pad and the Transformer. They are all pretty much the same.
What is post compiler?
A compiler translates anything that is a structured syntax, generally a computer language, into machine code or code that an interpreter will execute on a computer. Machine code actually executes on a machine, interpreted code is pure data for the execution engine of the interpreter.Post compilers, sometimes called post processors, take the compiled code as input and make changes to the code to provide functionality beyond that of the original language.Examples are:The original C++ language used a C compiler to process most of the file and a post compiler to add the object-oriented extensionsAspect Oriented Programming (AOP) functionality is generally added by a post compiler
What is oil transformer?
Transformer oil is pure insulating oil.
Can you load a transformer by a pure capacitive load?
No
Can you use a transformer to convert modified sine wave to pure sine wave?
we cannot use transformer because transformer cannot change frequency . . .
Why does pure silver remain shiny?
The surface was not altered by hydrogen sulfide.
Name of transformer oil?
An oil transformer is filled with PCB oil to better transfer heat from the windings to the outside case (and into the air).
What is the difference between simple and complex waveforms?
simple waveform - something like a sine wave. Very pure sound like you used to get on the tv when that girl was sitting with the toys in the middle of the night. Complex waveform is like speech etc
Can the inhalation of pure oxygen induce a state of euphoria or altered consciousness, commonly referred to as getting high?
No, inhaling pure oxygen does not induce a state of euphoria or altered consciousness like getting high. It can actually be harmful if done in excess.
Is it possible to experience a high or altered state of consciousness from inhaling pure oxygen?
Inhaling pure oxygen can increase alertness and improve cognitive function, but it does not typically induce a high or altered state of consciousness like drugs or other substances might.
What is the maximum DC voltage you could expect to obtain from a transformer with an 18V rms secondary using a full rectifier circuit with a filter capacitor?
25.46V assuming output of transformer is pure sinewave.

25.46V assuming output of transformer is pure sinewave.
Can a person use a transformer to convert modified sine wave into pure sine wave for off grids electrical suppy system?
A pure sine wave does not have any harmonic components beyond the fundamental. A transformer, if chosen carefully, could act as a low pass filter (removing the harmonics), but this is overkill. It would be better to develop a filter to do this.
What is a substance in its pure and natural form?
A substance in its pure and natural form is one that has not been altered or mixed with other substances. It exists in its original state as found in nature, without any additional processing or refinement.
