Terminal Voltage

Expert Answer:

We have P.D. across two ends as following in the two cases:

1)open circuit,   V=E

2)Closed cicuit,V=E-Ir  

In above,E=EMF of cell,r=internal resistance of cell,I=Current flowing when circuit is closed.

Clearly potential difference is more in case of open circuit then closed circuit.
