engineering recuitment MP ITI Training Officer Mock Test 2024 Physics Current, Resistance and Electricity Wheatstone Bridge
If the Wheatstone's bridge with four resistors R1, R2, R3, R4 is balanced then the correct expression is
1
\(\frac{\text{R}_2}{\text{R}_1} = \frac{\text{R}_4}{\text{R}_3}\)
2
\(\frac{\text{R}_2}{\text{R}_3} = \frac{\text{R}_1}{\text{R}_4}\)
3
R1R2 = R3R4
4
R1 + R2 = R3 + R4
