In a potentiometer,a balance point is obtained when:
- AThe $e.m.f.$ of the battery becomes equal to the $e.m.f.$ of the experimental cell.
- BThe $p.d.$ of the wire between the $+ve$ end and the jockey becomes equal to the $e.m.f.$ of the experimental cell.
- CThe $p.d.$ of the wire between the $+ve$ point and the jockey becomes equal to the $e.m.f.$ of the battery.
- DThe $p.d.$ across the potentiometer wire becomes equal to the $e.m.f.$ of the battery.

View Solution$A$ potentiometer is used to measure the potential difference between $A$ and $B$,and the null point is obtained at $0.9 \ m$. Now,the potential difference between $A$ and $C$ is measured,and the null point is obtained at $0.3 \ m$. Find the ratio $\frac{E_{2}}{E_{1}}$,given that $E_{1} > E_{2}$.
