Voltage drop is resultant of IR ie current and the line resistance, not dependent on impressed emf
An induced electromotive force (emf) is an induced voltage. Voltage (emf) causes current flow, and this induced voltage will cause a current that is called the induced current.We might also add that the induced current will cause a magnetic field to expand about the current path, and this field will "sweep" the conductor. The sweeping of the conductor by that expanding magnetic field will set up an emf that will oppose the emf that was creating it.CommentTechnically, there is no such thing as an 'induced current'. It is voltage that is induced. Any current flows as a result of that induced voltage being applied to a load. But that current is certainly NOT induced!
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
E. Joined in parallel, the voltage (or electromotive force, "emf") isn't additive. You'd get four times the current, or four times the life of a single battery, but it would have the same voltage.
Voltage drop
Opposition to voltage changes in a wire is called back EMF or counter EMF.See related links below.
In dc motor, the armature conductors are revolving in the magnetic field and emf is induced in the armature conductors. The direction of the induced emf is in opposite direction to the applied voltage as per Flemings left hand rule. So, the induced emf in motor is called as back emf or counter emf. Vydehi

There is analogy between pressure and EMF or voltage. What pressure is to the liquids, EMF or voltage is to electric current. But, of course, they are not the same.
the voltage of a battery could be larger than the emf if you are to charge the battery, in that case V=E+Ir .
EMF is electromotive force. It is another name for voltage. Voltage is electric potential in joules per coulomb. Current is electric flow, in amperes. Amperes are coulombs per second. Voltage and current are not the same thing, and "emf current", or "voltage current" does not make sense.

"Potential difference" or "Voltage".
EMF stands for Electro-Motive Force, commonly known as Voltage, measured in Volts.
Electro motive force = EMF = Voltage.
They call that "voltage" or EMF.
