2. Emf - Proper noun
the rate at which energy is drawn from a source that produces a flow of electricity in a circuit; expressed in volts
Source: WordNetAll solenoids and coils used on microprocessor games include a special reverse-biased diode to eliminate a high-voltage pulse of reverse EMF ( electromotive force ). Source: Internet
Both of these EMF's, despite their different origins, can be described by the same equation, namely, the EMF is the rate of change of magnetic flux through the wire. Source: Internet
However he only applied individual pulses of current to his transformer, and never discovered the relation between the turns ratio and EMF in the windings. Source: Internet
For example, an inductor with an inductance of 1 henry produces an EMF of 1 volt when the current through the inductor changes at the rate of 1 ampere per second. Source: Internet
He entrusted engineer Stanley with the building of a device for commercial use. citation Stanley's first patented design was for induction coils with single cores of soft iron and adjustable gaps to regulate the EMF present in the secondary winding. Source: Internet
