If the Wheatstone's bridge with four resistors \(R_1, R_2\) and \(R_3, R_4\) is balanced, then the correct expression is
- A \(\frac{R_2}{R_1}=\frac{R_4}{R_3}\)
- B \(\frac{R_2}{R_3}=\frac{R_1}{R_4}\)
- C \(R_1 R_2=R_3 R_4\)
- D \(R_1+R_2=R_3+R_4\)
Answer & Solution
Correct Answer
(A) \(\frac{R_2}{R_1}=\frac{R_4}{R_3}\)
Step-by-step Solution
Detailed explanation
For balance condition of Wheatstone bridge, \(\frac{R_2}{R_4}=\frac{R_1}{R_3} \quad \text { or } \quad \frac{R_2}{R_1}=\frac{R_4}{R_3}\)
