Answer / arun

When conductors cut magnetic field e.m.f get induced in it.

Voltage is the difference of electric potential measured in
between same point of a conductor or at different points.

Potential difference in between any two points is called as
voltage- same as above.

Current -Flow of electrons in a conductor or when a load is
connected in a circuit there will be a flow of electron
from high potential point to the low one.

Answer / karthik_elec

emf : electromotive force means voltage

voltage : the potential different between the two end of
the conductor that tends to create an current flow,
potential also voltage, definitions are same. or
the electrical presure applied to the electron to move one
place to other means voltage

Potential different: this is defined with respect to any
twopoints and it is measured in volts. numerically this is
equal to the work done in moving a coulomb of charge
between the two points.

current : the flow of electron from one place to other
place when electrical pressure applied it means current
