In an unbalanced Wheatstone Bridge, does the voltage across the resistors R1 and R2 change? In other words is V(adsbygoogle = window.adsbygoogle || []).push({}); _{R2}of balanced bridge=V_{R2 }of unbalanced bridge?

I was trying to solve a problem that required qualitative analysis. It says V_{R2 }does not change even though the bridge is unbalanced. How???

The Bridge Balance eqn is R1/R2 = R3/R4, where R4 is the variable resistor. At balanced condition, V_{R2}= V_{R4}
