What is EMF used for?
assuming you mean electromotive force: emf is the main principle behind power transformers. emf also comes in the form of radio waves, which are used for radio transmission (obviously)
How are emf measured?
emf in volts
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.
While discharging which is greater TPD or EMF?
EMF is greater
How do you prove the existence of back EMF?
How do you proof of the existence of back emf ?
Explain the principle of null-method of measurement?
The null method is used in measuring the unknown EMF of batteries. The method is about using a potentiometer circuit with the battery of a known and then an unknown EMF connected to it one after the other and locating, in each case, the position of the 'null point'; the point on the potentiometer circuit where the current through the battery is zero.
What happens to emf as a battery is used?
The emf of a batter as it is used will stay the same.

What is Least Cubic Method?
"Least Cubic Method" Also called "Generalized the Least Square Method", is new Method of data regression.
What is generalized least square method?
Generalized Least Square Method also called Least Cubic Method
What kind of soil conservation method is used least in Indiana?
Strip cropping
What is emf in physics?
emf is the electromotive force and is used as another word for voltage generated by a battery or by the magnetic force according to Faraday's law
What kind of soil conservation method is used least in New Jersey?
Strip cropping
What method of execution is used less in the United States?
Capital Punishment This is a major edit. The least used method of executions in the United States is the electric chair. The most "popular" method of execution is by lethal injection.
What is least square methode?
Generalized Least Square Method also called Least Cubic Method
How are emf measured?
