The EMF is the elcromotive force independent of current
flow but when the current stats flowing in the circuit then
there i some voltage drop due to the internal
resistense.So,The net potential difference will be V=E-IR
where V is the voltage,
E is Electromotive Force,
R is internal resistance.

Answer / abhishek-gaur

V=E-ir
there is som potential drop in internal resistnc of clll...
so terminal voltg is bit less

Answer / rakesh

it's necessary for curreny flowing in tha circuit .
beacause current flow high to low pd
, so that's required

Dear sir, we are getting voltage fluctuations suddenly for 2 or 3 minutes again it becomes normal. we checked each and every connection some times we are getting 110 volts like that from earth to neutral again it is reducing we are getting supply from 45 kva DG set give earthing properly.
