'it is emf when no current is flowing outside the cell. Whereas, it is potential difference is when current actually flows out of the cell."
"that emf is the potential difference when there is no current flowing through the circuit or when the key is open. Whereas, the circuit has certain value of potential difference when there is current flowing through the circuit."
i read it somewhere n i guess both mean the same... can someone please explain what, how, when, why (basically, everything about it)... in case they don't mean the same thing kindly explain both...
regards
