What is Full load current in transformer?
The no-load current of a transformer is the current which is drawn from the source at rated voltage and frequency even when no actual load current is being supplied.The no-load current is what must be drawn to overcome the inherent and unavoidable losses of the transformer's components. Those losses comprise the primary circuit's resistance (known either as the "copper losses" or as the "resistance losses") and the transformer's magnetic reluctance (known either as the "iron losses" or as the "magnetic losses").Reluctance is the techical description given to the energy necessary to excite the magnetic circuit and overcome its hysteresis, the effects of eddy currents, etc.For more information see the Related link shown below.
Why a transformer called machine?
The term "machine" in the context of a transformer may be a bit misleading, as a transformer itself is not a machine in the traditional sense. Here’s why a transformer might be referred to as a machine: 1. Electrical Device: A transformer is a type of electrical device that performs specific functions similar to machines. It changes the voltage and current levels in an electrical circuit, which is a form of electrical work. 2. Mechanical Analogy: In engineering terminology, "machine" can refer to any device or apparatus that performs work or a function. Transformers fit this broad definition because they perform the work of converting electrical energy from one voltage level to another. 3. Complexity and Operation: Although not a machine with moving parts, transformers are complex devices with multiple components (such as windings and cores) that work together to perform their function. This complexity might lead to the term "machine" being used informally. 4. Industrial Usage: In industrial and technical contexts, the term “machine” can sometimes be used to describe any equipment or apparatus involved in electrical or mechanical processes, including transformers. In summary, while a transformer does not fit the traditional definition of a machine with moving parts, it is often referred to as a machine in broader or industrial contexts due to its role and complexity in electrical systems.
What type of welding machine does not have positive and negative terminal connection?
Transformer type welding machine
What is stator of the armature?
The 'stator' is the generic term for the stationary parts of a machine, including its frame, magnetic circuit, poles, windings, etc.
Is there anyway to connect a 220V American commercial espresso machine to an American 110V outlet?
You cannot connect directly unless the espresso machine specifies it can operate at the lower voltage. If the machine were to operate you would be doubling the current. If you installed a transformer or converter to up the voltage you would have to ensure that you didn't overload the 110 volt circuit. Best bet is to have an electrician install a dedicated 220 volt circuit.

What is the difference between transfermer and generator?
They are both classified as electrical machines. However a generator is a 'rotating' machine, whereas a transformer is a 'static' (i.e., has no moving parts) machine. A generator converts one form of energy into another (kinetic to electrical), whereas a transformer simply transfers the energy supplied to its primary circuit to its secondary circuit while either stepping up, or stepping down, the primary voltage.

What type of welding machine does not have positive and negative terminal?
Transformer type welding machine
Which machine have very less losses in electrical?
Transformer
How is current controlled in welding transformer?
in welding machine, the transformer used is basically a current transforrmer. so by changing the tap of secondary side of transformer, we can increase or decrease the current in the transformer.
What did paul Lauterbur do for the MRI machine?
Type your answer here.. Dr. Lauderber came up with the concept of using graduated gradient magnetic fields on top of the primary static magnetic field to assign data to a specific place. The gradients slightly change the magnetic field in 3 planes.
What is the function of magnetic core in electrical machine?
The core, together with the machine's air gaps, form what is known as a 'magnetic circuit', which is a low-reluctance path that encloses the magnetic flux produced by its field windings, in order to concentrate that flux in the air gap through which the armature passes.
Why does a single phase AC series motor have a very short air gap?
All motors (and, indeed, generators) have a very narrow air gap. This is because the air gap forms part of the machine's magnetic circuit.A 'magnetic circuit' is the path in which the magnetic field produced by the machine's field windings is constrained, and is made up of silicon-steel in series with a very narrow air gap.Air has a very much higher reluctance (equivalent to resistance in an electric circuit) than the silicon-steel part of the magnetic circuit to the formation of flux and, so, must be kept as narrow as possible because reluctance is directly-proportional to the length of the air gap.
What is pole-shoe?
A pole shoe is a component in an electrical machine, often found in motors or generators, that forms part of the magnetic circuit to direct and shape the magnetic field. It helps concentrate and guide the magnetic flux produced by the machine's rotor or stator, enhancing its efficiency and performance.
What is the name of a machine in which the magnetic field is provided by an electromagnet?
MRI machine
What is a power transformer?
A transformer is a static machine utilized for changing force starting with one circuit then onto the next without evolving recurrence. This is an exceptionally fundamental meaning of transformer. The historical backdrop of transformer was started in the year 1880. In the year 1950, 400KV electrical force transformer was presented in high voltage electrical force framework. In the mid 1970s, unit rating as expansive as 1100MVA was delivered and 800KV and considerably higher KV class transformers were produced in year of 1980.
