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?
As a battery is used, its electromotive force (emf) decreases due to various factors such as internal resistance, chemical reactions, and depletion of the chemical components that generate the emf. This leads to a reduction in the voltage output of the battery over time as it discharges.
Why cant you use voltmeter 2 calculate emf of a cell?
A voltmeter measures potential difference across a component, which may not necessarily be equal to the EMF of a cell due to internal resistance in the cell and voltage drops across other components in the circuit. To accurately measure the EMF of a cell, a potentiometer or a high-resistance voltmeter is used in conjunction with a null point method.
How many Methods can be use to control the speed of Single Phase Induction Motor?
How many methods can be used to control the speed of Single Phase Induction Motor? 1.injecting emf method 2.by frequency control method 3.induced voltage method
Can iron absorb EMF?
No, as a conductor an EMF would be distributed through-out the metal body.
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 least square methode?
Generalized Least Square Method also called Least Cubic Method
Is lenz law used to find induced EMF's?
It's primary usage is to determine the nature of an induced EMF from changes in the magnetic flux through a circuit. However, you must use Faraday's Law (and a unit conversion factor) to determine the SIZE of such an EMF.
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.
