NEET Physics Wheatstone Bridge MCQ Question
Type: MCQ-numerical-Easy-Class 12
In a balanced Wheatstone bridge with resistors R1, R2, R3, and R4, if R1 = 100 Ω, R2 = 150 Ω, and R3 = 200 Ω, what is the value of R4?
A
300 Ω
B
75 Ω
C
133.33 Ω
D
50 Ω
Correct Answer
Option A
Detailed Explanation
According to the balance condition for a Wheatstone bridge, R1/R2 = R3/R4. Substituting the given values, 100/150 = 200/R4, solving for R4 gives R4 = 300 Ω.
