What is electromative force?
Electromotive force (EMF) is a term used to describe the voltage generated by a source of electrical energy, such as a battery or generator. It represents the driving force that pushes electric charges through a circuit. EMF is measured in volts and is often abbreviated as "E".
Can iron absorb EMF?
No, iron does not absorb electromagnetic fields (EMF) as it is a magnetic material. However, iron can be used to shield against EMF due to its magnetic properties.
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.
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 does the EMF of a battery which is made up of cells in series compare with the EMF of the individual cell?
The EMF of a battery made up of cells in series is equal to the sum of the EMFs of the individual cells. When cells are connected in series, their voltages add up. For example, if you have two 1.5V cells in series, the total EMF of the battery would be 3V.
What do the letters emf stand for?
for "ElectroMotive Force" . . . what we casually call "voltage".
What emf stands for?
Electromagnetic field (induces around the metal when current flows through it). Another opinion: Nope ! 'EMF' stands for 'Electromotive Force' . We refer to it casually as 'voltage'.
How are emf measured?
emf in volts
Is voltage used to make current flow?
Yes. Another term for voltage is EMF, electro-motive-force.
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....
Why do you measure emf with a potentiometer not with voltmeter?
EMF (E''electromotive Force'') is another term for Volts, hence the E in electronic formulas and EMF is measured with a volt meter. A potentiometer is not a meter at all, it is a variable resistor
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.
Is earths magnetic field slowly reducing?
Scientists are still struggling on what are the sources of earth's magnetic field (EMF). The facts support the notion that the EMF has reversed its direction several times in earth's history. When the EMF reverses, the EMF intensity will be weakened. Some evidence supports that the EMF intensity is now peaking and is due for a complete reversal in thousands of years. So yes, the EMF will be weakening. What we should worry about is what effects do the sun's activities have upon the EMF in our lifetime. The solar winds can weaken the EMF too. Scientists are predicting major solar activities coming (check the related link). ======================
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
What is the correct term when describing the frequency range 3 khz to 300 ghz?
Electromagnetic Frequency (EMF) & Radio Frequency (RF)
