What are the differences between potential difference and emf?
emf is present mainly in battery and potential difference is mainly present in circuit. emf is greater than p.d and p.d is greater than emf.......the units of both are Volt.....
Can iron absorb EMF?
No, as a conductor an EMF would be distributed through-out the metal body.
Emf produes when magnet is in motion does emf can be produced by rotating the coil?
EMF can be produced either by change of flux through a particular area kept in a magnetic field in a particular interval of time ( called self induced emf) or by the motion of any conducting rod in manetic fied....
What is the difference between CEMF and EMF?
Only the relative direction they are moving. EMF, measured in Volts, travels along a conductor, perhaps because a magnetic field has built up around the conductor. When that magnetic field collapses, CEMF, or counter-EMF is generated in the conductor, and it travels in the opposite direction of the original EMF, countering the original flow of electricity. EMF is Electromotive Force, and is one component of measuring electricity. EMF is measured in Volts, and represents the 'pressure' moving the electricity along.
Is emf a scalar or vector quantity?
Emf has direction within a current loop, though it is not scalar. It's a bit between though as direction should be otherwise accounted for when discussing induced Emf. Not quite either.
How are emf measured?
emf in volts
Why emf of battery driving potentiometer is greater than emf of the cell to be measured?
Bcoz the emf which is to be measured is less than emf of driving cell....
Does motional emf call induced emf?
yes indused emf is also called motional emf. If an open coil is subjected to a variable magnetic field, at the ends of the coil a potential difference is induced which is called induced emf. If a coil is connected to an emf source and switched on, the rising current will produced an variable magnetic field which in turn produces an emf. It is called back emf.
When did EMF - band - end?
EMF - band - ended in 2009.
When was EMF - band - created?
EMF - band - was created in 1989.
While discharging which is greater TPD or EMF?
EMF is greater
Unit of emf?
My physics teacher wrote out homework answers for us. On a few EMF problems, he has the EMF unit listed as Weber. On others, he has it as volts. I have a quiz tomorrow so I need to know which SI unit i'm supposed to use. Thanks! Few side notes: the formula we're using is E=delta I (subscript B) /delta t . There was no change in the formula for the different problems or what not. and somehow weber / time went to volts, other times it didn't. BY: VOLT
Do Emf waves travel at the speed of light?
What is the range of the EMF spectrum
How do you prove the existence of back EMF?
How do you proof of the existence of back emf ?
Do all emf waves travel at the speed of light?
What is the range of the EMF spectrum
When was Unbelievable - EMF song - created?
Unbelievable - EMF song - was created in 1990.
What happens to emf as a battery is used?
The emf of a batter as it is used will stay the same.
