Give me the relation between Potential difference V and E.M.F E

1.	Give me the relation between Potential difference V and E.M.F E
Answer» ${\bold{\underline{Hey \:Mate}}}$ Here's the Answer ❗ ${\boxed{\bold{Relationship\:Between\:E\:and\:<klux>V</klux>}}}$ =>When our electric circuit is open , there's no CURRENT flowing in it. Here we use the OHM's LAW that says that V = IR I = $\frac{V}{R}$ I = $\frac{E}{R}$ I = $\frac{E}{r+ R}$ I ( r + R ) = E Ir + IR = E Ir + V = E ${\boxed{V = E - Ir }}$ ${\bold{\underline{\underline{Hope \:Helps!}}}}$ _______________________________________________
