In a meter bridge a $30\;\Omega$ resistance is connected in the left gap and a pair of resistances P and Q in the right gap. Measured from the left, the balance point is 37.5 cm , when P and Q are in series and $71.4\;cm$ when they the parallel. The values of P and Q (in $\Omega$) are : - Clay6.com, a Free resource for your JEE, AIPMT and Board Exam preparation
