Answer / sil
EMF - Electro Motive Force.
"It can be defined as the Driving Force offered on the
electron to move from one potential to another".
Voltage - "It is defined termed as the potential difference
between the two nodes of an electric circuit".

Answer / jayadev and prasanth
emf is that force which tend to push electrons from one
poient to another . but voltage is the amount of current
passed through a given resistence.

Answer / soumya
EMF is the potential difference between two electrodes when current does not even starts to flow. Once the circuit is closed, it can never be called EMF. The native potential difference between two electrodes then are called voltage. In general voltage is little low than EMF of a circuit.

Answer / asra batool
EMF (Electromotive force) is the amount of workdone on a
unit charge which creates a potential difference across two
terminals so emf produces potential difference which is
called voltage
this voltage then creates electric field which results in a
current to flow across a wire

Answer / anitha
EMF is the external work expended per unit of charge to
produce an electric potential difference across two
open-circuited terminals.
EMF is measured in units called volts.

Answer / bothata
emf is a force acting whereas pd is the difference on
current
