Question

under which circumstances can the terminal potentiol diffenence of a battery eceeds its emf under which circumstances can the terminal potential difference of a b-tree exceeds its email EMF​

Answer 1

Answer:

This only happens when there is no load placed on the batterythat includes measuring the potential difference with a voltmeter. The terminal voltage will exceed the emf of the battery when current is driven backward through the battery, in at its positive terminal and out at its negative terminal.
