What is use of bushing in transformer?
A bushing is a hollow insulator, used with transformers and circuit breakers. It provides a means by which an energised conductor can pass from the outside to the inside of the transformer or circuit breaker.
Can you use electronic circuit as a load?
If you are just using the load to pull a small amount of current, then yes a electronic circuit can be used for that. If you want a resistive load to measure voltage drop or something similar, then no an electronic circuit will usually not work for that.
What the use of SMT in the manufacture of an electronic circuit?
to complete circuit
Introduction of clap switch?
This circuit can switch on and off light a fan or a radio etc;by the sound of a clap This circuit is constructed using basic electronic component like resistor transistor relay transformer capacitor .This circuit turns on light for the first clap . the light turns on till the next clap .for the next clap turns off this circuit works with 12v voltage . therefore a step-cown transformer 12v/300ma is employed. The working of the circuit is based on amplifying nature of the transistor . switching the nature of transistor and relay as an electronic switch.
What is a signal transformer?
Transformers are devices that use the principle of coupled magnetic fields to step voltage up or down, or provide DC isolation in circuits. A signal transformer is a special application of a transformer that is used to couple a signal from one circuit into another circuit. The signal might be stepped up (or amplified), or it might be stepped down, or it might be coupled without an increase or decrease simply to provide isolation, impedance matching, or phase shifting from stage to stage in an electronic device.
What is the reason to use open circuit and short circuit methods to find Transformer losses?
The transformer can be tested on open and short circuit to find the iron losses and copper losses separately, which uses a fraction of the power than having to run the transformer on full-load.
Why low power factor wattmeter is used for open circuit test of transformer?
For open circuit test of transformer, the secondary is open circuit and the circuit impedance is largely inductive due to the core impedance having high L as compared to R. hence the power factor is reduced, thus , we use low power factor wattmeters.
What do you use to measure voltage in an electronic circuit?
A Voltmeter.
Why transformer action can take place in DC circuit?
Not clear what your question is. First of all, circuits are not classified as DC and AC. Circuits are what they are, and you can apply either AC or DC to any circuit. However, considering a circuit that was designed only for use with DC applied. Still your question is unclear. What is transformer action? "Transformer Action" happens in a transformer.
What is the use of a transformer with turns ratio 1?
isolation if you are in the usa and must service electronics the neutral is grounded the power supply is a voltage doubler one side is 170v+ to ground the other is 170v negative to ground so if you run the power thru the transformer first you stand a better chance of staying alive these transformers are quite often used to trigger scrs or triacs for the same reason
Where is the use of earth transformer?
It is used in where the transformer are connected in star delta.
Why do you not use potential transformer?
Your question is rather oddly phrased as, obviously, there are countless ways in which you wouldn't use a potential transformer! It's much easier to explain why you would us a potential transformer. A potential transformer (known outside North America as a 'voltage transformer') is classified as an instrument transformer, which means that its output is used to drive instruments, such as voltmeters and (the voltage coils of) wattmeters, etc., or to provide inputs to protective relays. It's function is twofold: (1) to reduce the high voltage of the circuit to which its primary winding is connected to a lower voltage which can be 'read' by a voltmeter, etc., and (2) to electrically-isolate its secondary circuit from the primary circuit for the purpose of safety.
