it is because earlier it was thought to be a force inside a battery that takes the electrons from lower potential terminal to higher one in a mysterious way and hence a force . But , now we know that emf is the external work expended per unit of charge to produce an electric potential difference across two open-circuited terminals . And the electrons do so due to the electric field inside the battery..
What else can I help you with?
Do all emf waves travel at the speed of light?
What is the range of the EMF spectrum
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.
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.
Why the terms shooting star and meteor are misnomers?
Shooting star is a misnomer because it shoots through space but it's not a star, it's an asteroid. Meteor is'nt a misnomer.
To measure EMF you would use a(n)?
"voltmeter"
It can be said that pressure and electromative force are the same?
There is analogy between pressure and EMF or voltage. What pressure is to the liquids, EMF or voltage is to electric current. But, of course, they are not the same.
How do you use misnomer in a sentence?
Don't misnomer my name.
What is an example of a misnomer?
A misnomer is a wrong or inaccurate name or designation; "king crab" is a misnomer-these creatures are not crustaceans at all.
Use misnomer in a sentence?
the retard is a very misnomer name
When was The Madison Misnomer created?
The Madison Misnomer was created in 2007.
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.
While discharging which is greater TPD or EMF?
EMF is greater
When was EMF - band - created?
EMF - band - was created in 1989.
When did EMF - band - end?
EMF - band - ended in 2009.
Do Emf waves travel at the speed of light?
