My physics teacher wrote out homework answers for us. On a few EMF problems, he has the EMF unit listed as Weber. On others, he has it as volts. I have a quiz tomorrow so I need to know which SI unit i'm supposed to use. Thanks!
Few side notes: the formula we're using is E=delta I (subscript B) /delta t . There was no change in the formula for the different problems or what not. and somehow weber / time went to volts, other times it didn't.
BY: VOLT
EMF (Electro Motive Force) is measured in volts.
volt or jper coulomb
the unit of "e.m.f" is "volt"
volts abbr (V)
emf in volts
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.
EMF is greater
the unit of "e.m.f" is "volt"

EMF stands for Electro-Motive Force, commonly known as Voltage, measured in Volts.
volts abbr (V)
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.
Both emf and pd have the same unit. namely volt Both have the same definition. It is the work performed in moving unit positive charge right from one point to the other against the electric field. Both are got by the product of current and resistance. But emf is the pd across of a cell or source when it is not in action. So emf is slightly greater than the pd in the circuit as there may be a little bit of internal resistance.
The SI unit of EMF (electromotive force) in a direct current circuit is Volts. The circuits current is measured in ampere's
emf has SI units of volts, equivalent to joules per coulomb.
emf in volts
Bcoz the emf which is to be measured is less than emf of driving cell....

You don't. If you know how many Amperes in an electrical circuit and also what the total resistance in the circuit is, then EMF (Volts) = current (Amps) x resistance (in Ohms). EMF stands for Electromotive Force, and its unit of measure is the Volt.
