Questions
In the potentiometer arrangement shown in figure, null point is obtained at length l.
| Column I | Column II | ||
| i. | If E1 is increased | p. | l should increase |
| ii. | If R is increased | q. | I should decreases |
| iii. | If E2 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.
detailed solution
Correct option is B
For potentiometer circuit, E=xl1x depends only on primary circuiti E1 ↑ ⇒ x↑ ⇒ l1 ↓ if secondary circuit remains sameii R ↑ ⇒ x↓ ⇒ l1 ↑ if secondary circuit remains sameiii E2 ↑ ⇒ l1↑ if x remains sameTalk to our academic expert!
