IGCSE Grade 10 Science Electromotive force
|
Watt-hour is the voltage multiplied by the current for some amount of time.
EMF equation of a transformer
\\(E = 4.44f\\phi _{m}N\\)
EMF is the voltage generated by the magnetic force according to Faraday's law.
In static-induced emf conductor remains static and the magnetic field changes.
The transformers with this ratio between primary and secondary windings are used to protect secondary circuits and individuals from electric shock.
Fleming's right hand rule.
Induced emf is directly proportional to the number of turns, magnetic field, area, and time in which the magnetic flux changes.
Potential difference creates an electric field that causes the charge to move which creates a current.
It resists the change of current flowing through the coil.
EMF is the amount of energy supplied by a battery per coulomb of charge passing through it.
