Question

In the meterbridge experimental set up, shown in the figure, the null point 'D' is obtained at a distance of 40 cm from end A of the meterbridge wire. If a resistance of 10 $\Omega$ is connected in series with $R_{1}$, null point is obtained at AD = 60 cm. Calculate the values of $R_{1}$ and $R_{2}$.

Answer 1

the null point 'D' is obtained at a distance of 40 cm from end A of the meterbridge wire. If a resistance of 10 \OmegaΩ is connected in series with R_{1}R1​ , null point is obtained at AD = 60 cm. Calculate the values of R_{1}R1​ and R_{2}R2​ .
