WHAT IS the difference between ELECTRO MOTIVE FORCE(emf) AND VOLTAGE

Question

espex · Answer

Electromotive force is the potential difference of charge across a source while voltage is the potential difference across terminals in a closed circuit.

@ eSpeX can you please relate EMF and voltage to Electrons. Explain.

anonymous · Answer

Electromotive force is the work done to move a unit charge across the terminals of a battery.
Voltage is the potential difference across the terminals of the battery.
They are numerically equal if the internal resistance of the battery is zero or if there is no current.
Else, while discharhing, V= E- ir
While charging, V= E + ir
E is the emf, r is the int resistance

Actually,
EMF is the potential difference across two terminal ends of a battery or cell in an OPEN circuit. EMF stands for Electro Motive Force.

V or Potential difference is the potential drop across tow terminal ends of a battery in a closed circuit.

anonymous · Answer

basically the sames thing with different views in physics.
to a voltage supply, there is no differences.
in the case of circuit, voltage is more general because voltage can be measured between different nodes while emf cannot.
if you can't understand it right now, just stop thinking. you will in the future finally.
