Q.
In the potentiometer arrangement shown in figure, null point is obtained at length $l$.
Column I
Column II
i
If $E_{1}$ is increased
p
$l$ should increase
ii
If $R$ is increased
q
$l$ should increase
iii
If $E_{2}$ is increased
r
$l$ should remain the same to again get the null point
Now, match the given columns and select the correct option from the codes given below.
Column I | Column II | ||
---|---|---|---|
i | If $E_{1}$ is increased | p | $l$ should increase |
ii | If $R$ is increased | q | $l$ should increase |
iii | If $E_{2}$ is increased | r | $l$ should remain the same to again get the null point |
