Engineers often use 'models' to represent the behaviour of complicated devices such as machines. In the case of Transformers, these 'models' are more-usually called 'equivalent circuits' -schematic diagrams, using simple resistors and inductors, to simulate the operation of the transformer, and to help us construct the transformer's phasor diagrams.
The simplest equivalent circuit, which can be considered a 'first approximation' of the transformer's behavioiur, is commonly called an 'ideal transformer', and only accounts for the transformer's ability to step up or step down the primary voltage and secondary current.
The 'second approximation' equivalent circuit, takes into account the core losses and magnetising current.
The 'third approximation' equivalent circuit takes into account the resistance and leakage reactance of the primary and secondary circuits, responsible for the regulation of the transformer, and it takes into account both the core losses and the copper losses. The 'third approximation' equivalent circuit, therefore, can be considered the most accurate equivalent circuit.
What else can I help you with?
Is tram close circuit or open circuit?
If the circuit was open, the tram's motor could not run!
How can you draw electric circuit in Microsoft Word?
It's very easy to draw an electric circuit in Microsoft Word. You just need to open up the graphics menu from the top, and you'll get access to the drawing tools for circuit drawing.
What is a closed circuit?
A closed circuit is a kind of electric circuit in which the path that the electrons follow forms a complete circuit.
A circuit flow on a open switch?
no because when you close it, the circuit is complete so it lets the electrons pass through
What opens or closes an electrical circuit?
That function was traditionally implemented in the form of a mechanical deviceknown as a "switch".The practice became so firmly embedded in the art and science of electricitythat the word became the generic term for any device that could performany similar function, so that now we have "switching transistors", integrated"CMOS switches", and even central office telephone-circuit "switches".
Used to open and close a circuit?
A light switch
What to do if there is an open in the circuit?
Close it!!
Is tram close circuit or open circuit?
If the circuit was open, the tram's motor could not run!
How can one close an open circuit?
One can close an open circuit by adding a complete loop of wire. This will allow the electricity to flow through the circuit, while electricity will not flow in an open circuit.
What are the switches in the circuit use for?
To open and close the circuit.
What are the switches in the circuit used for?
To open and close the circuit.
What do a switch do for the circuit?
It open and close it
Many circuits have a which is a device to open and close the circuit.?
A basic manual operating switch is able to open or close a circuit. There are electronic components that will also control the working of a circuit.
Is Circuit City open on Christmas day?
no circuit city is close on Christmas day
What device will open or close the break in a electrical circuit?
A switch.
Does howrah bridge open and close?
it didn't open, because its never a draw bridge.
