A balance point in a meter bridge experiment is obtained at 30 cm from the left. If right gap contains 3.5Omega, what is the resistance in the left gap?

Answer»

Solution :The balancing length from left `L=20cm`
RESISTANCE in right gap `R=3.5Omega`
`R=Sxx(l)/((100-l)),R=3.5xx(30)/(70)rArr R=1.5Omega`
