In a Wheatstone bridge, BALANCE condition gives:

Question

Accepted Answer

C. R₁R₃ = R₂R₄

**Balance condition:** P/Q = R/S (in standard notation).
Equivalent to R₁R₃ = R₂R₄ depending on labelling.
The key relation is cross-products of resistors are equal at balance.

Answer

R₁R₂ = R₃R₄

Answer

R₁/R₂ = R₃R₄

Answer

R₁ + R₂ = R₃ + R₄

In a Wheatstone bridge, BALANCE condition gives:
