What are the difference between these terms ? e.m.f,
voltage, potential, potential difference, current etc?
what are the difference between these terms ?
(electromotive force) e.m.f, voltage, potential, potential
difference, reference potential, reference potential
difference, current.
How can i explain and describe these all terms in single
line each and little more explaination too
thanks

Answer Posted / 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
