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)
What else can I help you with?
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 ?
What does the emf equation of asingle phase transformer do?
The emf equation of signal phase transform
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.
Can iron absorb EMF?
No, as a conductor an EMF would be distributed through-out the metal body.
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.
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.
What is emf in physics?
EMF, or electromotive force, is a measure of the energy provided by a source (such as a battery) to move a unit charge around a closed circuit. It is responsible for driving the flow of electric current in a circuit. EMF is measured in volts.
What is an EMF detector used for and how does it help in detecting electromagnetic fields?
An EMF detector is used to measure and detect electromagnetic fields. It helps in identifying sources of electromagnetic radiation, such as electrical wiring, appliances, or electronic devices. The detector works by picking up changes in the electromagnetic field strength and alerting the user to potential sources of EMF exposure.
How do you prove the existence of back EMF?
How do you proof of the existence of back emf ?
