What is the phase difference between stator mmf and rotor mmf?
The phase diference is proportional to the load
Difference between voltage and emf?
'Voltage' is simply another term for 'potential difference', and an electromotive force is the open-circuit, or no-load, potential difference of a source such as a battery or generator.
What is mmf?
Full-form Of MMF: MAGNETO MOTIVE FORCEDefinition Of MMF ( Magneto motive Force ): Just as electromotive force ( emf ) is necessary to pass current in electric circuit, magneto motive force ( mmf ) is necessary to establish flux in the magnetic circuit. Magneto motive force is the multiplication of current flowing through the coil and the number of turns of the coil.Unit of magneto motive force ( mmf ) is ampere turn.Thus, it should be understood that the magneto motive force can be increased by increasing the number of turns in the coil or by increasing the current flowing through the coil or by increasing both.CommentThe unit of measurement of magnetomotive force is actually the ampere, although it is frequently spoken as 'ampere turn' to prevent its confusion with electric current.
What symbol is used to measure potential difference?
V which abbreviates the word volt, which is the unit of measure of the difference in electromotive force (EMF), (or electric potential) between two points of contact; the resulting voltage difference could be direct current (DC) or alternating current (AC) depending on the source of the voltage difference.
Difference between statically and dynamically induced emf?
STATICALLY INDUCED EMFThe emf induced in a coil due to change of flux linked with it (change of flux is by the increase or decrease in current) is called statically induced emf.Transformer is an example of statically induced emf. Here the windings are stationary,magnetic field is moving around the conductor and produces the emf.DYNAMICALLY INDUCED EMFThe emf induced in a coil due to relative motion of the conductor and the magnetic field is called dynamically induced emf.example:dc generator works on the principle of dynamically induced emf in the conductors which are housed in a revolving armature lying within magnetic field

What are the differences between potential difference and emf?
Potential difference is the difference in electric potential energy between two points in a circuit, while electromotive force (emf) is the total energy provided per unit charge by a battery or voltage source. In other words, potential difference measures the voltage drop across a component in a circuit, while emf represents the energy per unit charge supplied by the source.
What is the relationship between EMF and potential difference in an electrical circuit?
The relationship between EMF (electromotive force) and potential difference in an electrical circuit is that EMF is the total energy supplied by a source, while potential difference is the energy transferred per unit charge as it moves through the circuit. In simpler terms, EMF is the total push provided by the power source, while potential difference is the push experienced by the charges as they flow through the circuit.
How is Ohm's Law for Magnetism analogous to voltage EMF?
Magnetomotive force (not 'magneticmotive force') is analogous to electromotive force, in the same way that magnetic flux is analogous to current, and reluctance is analogous to resistance. Mmf, flux, and reluctance also have the same 'Ohm's law' relationship as emf, current, and resistance. It is mmf that sets up the magnetic flux; it is the emf that sets up the current.One point worth noting is that despite mmf being measured in amperes (the product of the current flowing through a coil and the number of turns), it is still analogous to emf, and not current!
What is the difference between Counter-electromotive force and back emf?
They are Same for dc motor
What is the difference between the emf of a battery and the lost volts when discharging called?
Internal resistance
In colomn answer of difference between statically indused emf and dynamicaly indused emf?
Statically induced emf is produced by the relative motion between a conductor and a magnetic field, while dynamically induced emf is generated due to a change in the magnetic field strength experienced by a conductor. Statically induced emf does not require any physical movement of the conductor, while dynamically induced emf is produced when the magnetic field changes over time.
What is the difference between an .emf file and an .mmf file?
Emf file is a vector image file. Generic vector graphics format recognized by several image-editing applications; a 32-bit version of the original Windows Metafile Format (.WMF), which only supports 16-bit data; saves image data in an RGB format and does not support CMYK data. Mmf file is a Synthetic Music Mobile Application File. Yamaha SMAF sound file format created for mobile devices; commonly used for cell phone ring tones, but also supports the display of text and graphics; can be created from .WAV or .MID files using Yamaha SMAF Tools.
What is the reason for the distance limitation with the use of mmf?
MMF can stand for lots of things. What is MMF?
What is the term for he phenomenon of emf development between two different metals placed in contact?
The term for the phenomenon of emf development between two different metals placed in contact is called the thermoelectric effect. This effect occurs because of the temperature difference between the two metals, which creates a potential difference or voltage.
Difference between voltage and emf?
'Voltage' is simply another term for 'potential difference', and an electromotive force is the open-circuit, or no-load, potential difference of a source such as a battery or generator.
What is the potential difference between two points in a circuit is called?
Voltage drop
