Questions
In meterbridge experiment when a resistance wire is connected in the left gap, the balance point is found at 30 cm. When the wire is replaced by another wire, the balance point is found at 60 cm. Find the balance point when the two wires connected in series.
detailed solution
Correct option is A
R1R=3070=37&R2R=6040=32;R1+R2R=37+32=6+2114=2714⇒2714=n(100−n) 2700=(27+14)n⇒n=270027+14≈65.9cmTalk to our academic expert!

In a meter bridge experiment, the null point is obtained at 20 cm from one end of the wire when resistance X is balanced against another resistance Y. If X <Y, then where will be the new position of the null point from the same end, if one decides to balance a resistance of 4X against Y ?
