Physics-Wheatstone Bridge
NEET Physics Wheatstone Bridge Match the Following Question
Type: Match the Following-match the column-Easy-Class 12
Match Column-I with Column-II.
Column-I Column-II (a) Balanced bridge (i) I 1 = I 3 (b) Unbalanced bridge (ii) I 2 = I 4 (c) Null deflection (iii) No current through galvanometer (d) Galvanometer reading (iv) Indicates resistance difference
Choose the correct matching:
A
a-i, b-ii, c-iii, d-iv
B
a-ii, b-i, c-iv, d-iii
C
a-iii, b-iv, c-i, d-ii
D
a-iv, b-iii, c-ii, d-i
Correct Answer
Option A
Detailed Explanation
In a balanced Wheatstone bridge, the currents I 1 and I 3 are equal, and I 2 and I 4 are also equal, leading to no current through the galvanometer, which indicates a null deflection. This is the condition for determining unknown resistances.
