Why transformer core is of magnetic not of wooden?
The transformer core is ferromagnetic in order to focus and concentrate the magnetic fields generated in the windings. This improves coupling and increases inductance.
What are the types of coupling in software engineering?
control coupling content coupling common coupling data coupling external coupling message coupling
What are types of mechanical coupling?
There are many like flexible coupling, jaw coupling, sleeve coupling, tire coupling, pin and bush coupling, rigid coupling, etc
Which coupling gives high gain in case of amplifier?
no.transformer coupling gives higher gain
Which Coupling produces minimum interference with frequency response?
Direct coupling
What is meant by coupling magnetic field in electromechanical energy conversion?
Coupling field is link between electrical and mechanical energies in electromechanical energy conversions. If the output is mechanical (motor), coupling field reacts with input electrical energy in terms of Back EMF which opposes the input. Coupling field absorbs energy from electrical system, converts and delivers mechanical energy. If output is electrical (generator), coupling field reacts with input mechanical energy in terms of Magnetic Drag which opposes the input. Coupling field absorbs energy from mechanical system, converts and delivers electrical energy.

What is meant by mutual coupling?
conection between two or more magnetic circuits magnetically with out any electrical connection .i.e.'flux linkages are there inbetween the magnetic circuits.

What is coupling in electronics?
AC coupling is where a capacitor is used to block the DC componant of a signal. Used often in Medical devices when a DC componant could harm a patient Coupling refers to transferring electrons trough a media. It could magnetic such as coils proximity. A transformer and yes even a capacitor. And no it has no medical devices ONLY application.
What flux that does not follow the intended path in a magnetic circuit?
Leakage flux is the flux that does not follow the intended path in a magnetic circuit. It represents the magnetic field that strays outside of the core and does not contribute to the desired magnetic coupling between the components of the circuit. Strategies such as improving the design and materials of the magnetic circuit can help minimize leakage flux.
Which coupling gives the higher gain in case of amplifier - a Capacitor coupling b Impedance coupling c Transformer coupling?
transformer coupling
Resolution effect on nuclear magnetic resonance spectrum?
Resolution is affected by the strength of the B0 magnetic field. The j coupling (distance between lines in a quartet for instance) is a constant value in Hz. However the place that the lines appear is not. Increasing the magnet increases the distance between features while keeping the j coupling from overlapping (thus allowing independent, resolved peaks
Why most practical energy conversion devices used magnetic field as the coupling medium between electrical and magnetic system?
Magnetic fields are commonly used in energy conversion devices because they allow for efficient energy transfer between electrical and mechanical systems. This coupling medium enables devices such as electric motors and generators to convert electrical energy into mechanical energy (and vice versa) with minimal energy loss. Magnetic fields help create rotation or linear motion, making them versatile and widely used in various applications.
What is the importance of residual flux?
Residual flux refers to the magnetic field remaining in a material after the removal of an external magnetic field. It is important in applications like transformers and electric motors, as it helps maintain the efficiency of these devices by ensuring continuous magnetic coupling. Residual flux also affects the hysteresis loop of a material, influencing its magnetic properties.
What is RC coupling?
rc coupling is a coupling that involves capacitor aand resistor
