In which conditon E.m.f. gets equal to potential difference?

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

Under what condition will be terminal petential difference be more than the e.m.f. of a cell?

The dimensional formula of potential difference is

The capacitances of two capacitors are 2 mu F and 8 mu F . They are connected in series and a potential difference of 100 V is applied across the combination. What are The potential differences across the two capacitors?

A Wheatstone network ABCD contains equal resistances P in the arms AB and CD and equal resistance Q in the arms AD and BC. A cell of e.m.f. 1 V and negligible resistance is connected across AC. Calculate the potential difference between B and D.

E.M.F. of electrical cell is 2 volt. A 10Omega resistance is joined at its two ends then potential difference in measured 1.6 volt. Find out the internal resistance and lost volt.

How can two capacitors be connected so that the potential differences between their plates are equal?

Two capacitors of capacitances 0.5 mu F and 0.75 mu F are connected in parallel. A potential difference of 600 V is applied to this combination. What are the charges on the two capacitors? Now, the two capacitors are connected in series and the same potential difference is applied. Find out the charges on the capacitors in this case.

Write three difference between e.m.f and potential difference.
