Is voltage a force? Pressure? Potential? Why voltage is called electro motive force at generation?
1)Electromotive force, abbreviated emf is the electrical intensity or "pressure" .
2)Voltage is electric potential energy per unit charge, measured in joules per coulomb ( = volts). ... A to B. When a voltage is generated, it is sometimes called an "electromotive force" or emf. ... Analogy with pressure in water circuit ... (voltage) which has been made available by the generatingmechanism and is not a "force".
Voltage is the potential difference between any two points.
If you keenly observe the term ' electro-motive force' with its literary meaning:
Electro means electrical energy
Motive is related to motion
Force is the driving source for any motion.
So it is called electromotive force at generation because it is the drives current(i.e. a form of electrical energy) into the circuit.
