It is mostly historic. Voltage is the potential difference, whereas your wouldn't describe it as something that acts as an EMF (a source of voltage), although if you consider Maxwell's work, he claimed that potential differences can act as EMFs.And if they are "one in the same" then why do we use different names for them????
Sure is, an EMF source is measured in volts.Isn't it true that Volts is a unit of measure used when referring to an emf. A volt is defined as the emf developed across 1 Ohm with 1 Amp of current flowing through it.

Yes, but remember to keep it in context. If you put the VM in parallel around the EMF source you will measure the voltage of the source."Potential difference is relative between two points", it is quoted it in the first chapter i think.Keeping this in view can we say the same for emf? And if emf is just related to a source,then is it right to say that voltmeter measures emf?
Sir i was not beaten to your reply.My internet has a frustratingly slow speed.Beaten to the answer!

Sorry, I meant someone answered your question before I did (I was too slow in giving an answer!)Sir i was not beaten to your reply.My internet has a frustratingly slow speed.
Since EMF is measured in Joules per Coulomb or energy per unit charge, then yes I would agree - Maxwell certainly did!the term Electromotive force is a sort of misnomer..its not a force, its an energy IIRC.
By that logic... would mass be energy? - measured in Joules per square V?Since EMF is measured in Joules per Coulomb or energy per unit charge, then yes I would agree - Maxwell certainly did!
