Is it possible that there is no potential difference between the paltes of a cell ? If yes, under what condition?

What causes the potential difference between the two terminals of a cell?

Under what condition will the terminal potential difference be more than the emf of a cell?

A parallel plate capacitor of capacitance 2 muF is fully charged to a potential difference of 500 volts and then disconnected from the battery. Using insulating handles, separation between the paltes is made thrice the initial value. What will be the new potential difference between the plates of the capacitor and by what amount stored energy changes in this process?

What is the difference between electrode potential and cell potential?

What is the difference between emf and potential difference?

Is it possible for any process to have DeltaH = DeltaE ? If yes, state under what conditions? If no, state why not?

What is the difference between cell potential and standard cell potential ?

What is the difference between emf of a cell and potential difference of a cell?
