NEET Physics Wheatstone Bridge MCQ Question
In a Wheatstone bridge, resistors R1, R2, R3, and R4 are connected in a diamond shape, with a galvanometer connected between the midpoints of two opposite sides. If the bridge is balanced, which equation represents the condition that results in zero deflection of the galvanometer?
R1/R2 = R3/R4
R1/R3 = R2/R4
R1/R4 = R2/R3
R1/R2 = R4/R3
Correct Answer
Detailed Explanation
The balance condition for a Wheatstone bridge, given in the NCERT context, is R1/R3 = R2/R4, which ensures no current flows through the galvanometer.
