152860 Two students $X$ and $Y$ perform potentiometer experiment separately and null point was obtained as shown in diagram. During the experiment,
(i) $\mathrm{X}$ increases the value of $\mathrm{R}$ (resistance)
(ii) $Y$ decreases the value of $S$ (resistance)
The position of null point obtained by students $X$ and $Y$ respectively'

1 would shift towards point B, would shift towards A
2 would shift towards B by both X and Y
3 would shift towards point $A$, would shift towards B
4 would shift towards A by both X and Y

152863 The current through $1 \Omega$ resistance in the following circuit is

1 $1.5 \mathrm{~A}$
2 $0.9 \mathrm{~A}$
3 $1.3 \mathrm{~A}$
4 $1.1 \mathrm{~A}$
Current Electricity

152864 A potentiometer is used to measure the potential difference between $A$ and $B$, the null point is obtained at $0.9 \mathrm{~m}$. Now potential difference between $A$ and $C$ is measured, the null point is obtained at $0.3 \mathrm{~m}$. The ratio $\frac{E_{2}}{E_{1}}$ is $\left(E_{1}>E_{2}\right)$
